Do you want MSAdvance to handle your migration from Microsoft Teams to Google Chat?
Moving from Microsoft Teams to Google Chat is not just about “copying messages”. It is a transition in the way people work: channels become spaces, files need to be placed correctly, and users need to understand where to talk, where to search and how to collaborate.
At MSAdvance, we design and execute the migration from Teams to Google Chat with an end-to-end approach: assessment, team and user mapping, Google Workspace configuration, conversation import, validation, communication and adoption support.
- Inventory of Teams, channels, owners, members, files and dependencies.
- Target design in Google Chat: spaces, permissions, naming, retention and governance.
- Migration with Google native tools or specialized solutions when the case requires it.
- End-user support so that the change is understood and adopted.

Migrating Teams to Google Chat is the process of moving Microsoft Teams channel conversations to Google Chat spaces, together with user mapping, team structure, permissions, linked files and retention rules. Google lets you import Teams channel messages from the Google Workspace Admin console, but not everything is migrated natively: for example, 1:1 chats, certain attachments, bot messages, stickers or some advanced formats require specific handling, an alternative export or third-party tools.
Quick summary: Teams to Google Chat migration in 9 points
- What can be migrated: Microsoft Teams channel messages to Google Chat spaces, with user and team mapping.
- What should not be overpromised: not all chats, attachments, bots, reactions or formats are transferred in the same way as in Teams.
- The key is not only technical: you need to redesign how work will happen in Google Chat, Google Drive and Google Workspace.
- Channels become spaces: the Teams structure should be reviewed before copying it as-is.
- Users must exist in Google Workspace: with active licenses, Google Chat enabled and correct identity mapping.
- Files need their own strategy: Teams uses SharePoint/OneDrive; in Google Workspace, the usual approach is to move them to Google Drive or shared drives.
- The migration can be phased: pilot, initial import, delta, validation and space rollout.
- Security matters: Google Vault, Chat history, retention, DLP and permissions must be prepared before importing.
- A partner reduces risk: especially when there are many teams, external users, legal requirements or a need for minimal disruption.
When does it make sense to migrate Teams to Google Chat?
Not every organization needs to migrate the entire Teams history to Google Chat. Sometimes it is enough to keep Teams in read-only mode for a period, export specific evidence or start in Google Chat with new spaces. But there are scenarios where a Microsoft Teams to Google Chat migration delivers significant value.
Common scenarios
- Complete migration from Microsoft 365 to Google Workspace: moving from Outlook, Teams, OneDrive and SharePoint to Gmail, Google Chat, Drive and Meet.
- Tool consolidation: the organization wants to reduce costs and avoid maintaining Teams and Google Chat in parallel.
- Mergers or acquisitions: one company works in Microsoft 365 and another in Google Workspace, and the decision is made to unify on Google.
- Change in collaboration strategy: the company adopts Google Workspace as its primary platform and wants to bring over the most important workspaces.
- Continuity needs: teams need to consult historical conversations from projects, support or customers inside the new environment.
- Governance and security: the goal is to centralize retention, eDiscovery, DLP and data control in Google Workspace.
The practical question is not “can everything be migrated?”, but what is worth migrating, what should be archived and what is better recreated from scratch. Copying years of noise into Google Chat does not improve productivity. Migrating useful content, properly organized and with context, does.
Introduction: what changes when moving from Teams to Google Chat
Microsoft Teams and Google Chat are similar in some ways, but they are not the same. In Teams, work is usually organized into teams and channels, with files hosted in SharePoint or OneDrive. In Google Chat, the center of collaboration is spaces, integrated with Gmail, Drive, Calendar, Meet, Docs, Sheets and the rest of Google Workspace.
That is why a Teams to Google Chat migration should not be approached as a literal copy. Ideally, the change should be used to clean up: remove abandoned channels, review permissions, decide which conversations have value and prepare a simpler user experience.
The common mistake is to think only about messages. But messages are just one part. You also need to look at files, mentions, owners, external users, compliance, retention, links, integrations, bots and working habits.
An operations team may have a Teams channel with years of conversation, attachments, SharePoint links, mentions and important decisions. When migrating it to Google Chat, it is not enough to move text: you need to make sure the new space has the right members, the documents are in Drive, the key links make sense and the team knows where to continue working.
1. Project methodology and governance
In practice: a Teams to Google Chat migration works best when it is executed in waves, with a pilot, validation and clear communication.
Migrating conversations should not become an uncontrolled “big bang”. The recommended methodology is to move forward in phases: first understand the environment, then define the destination, test with a pilot and only then scale.
Recommended phases
- Assessment: inventory of teams, channels, users, owners, activity and dependencies.
- Target design: Google Chat space structure, naming, memberships, permissions and retention.
- Pilot: migrate a small but representative set of teams.
- Waves: progressive migration by area, department or criticality.
- Delta and cutover: import recent messages before opening spaces to users.
- Adoption: support, training and issue tracking.
| Activity | Responsible | Approves | Consulted | Informed |
|---|---|---|---|---|
| Teams inventory | MSAdvance / IT | IT | Business | Key users |
| Google Chat space design | MSAdvance | IT / Business | Security | Users |
| Identity mapping | IT | IT | MSAdvance | Business |
| Import and validation | MSAdvance / IT | IT | Team owners | Users |
| Adoption and support | MSAdvance / Business | Management | IT | Entire organization |
2. Assessment: Teams inventory before migration
In practice: before migrating Teams to Google Chat, you need to know which Teams exist, which ones are used and which ones only add noise.
A good assessment prevents two problems: migrating too much and migrating badly. Not all Teams have the same value. Some contain critical conversations, while others are abandoned spaces, old tests or duplicates.
What the inventory should include
Teams and channels
- Team name and associated channels.
- Channel type: standard, private or shared.
- Last activity and message volume.
- Owners and active members.
Users and permissions
- Internal and external users.
- Members who are no longer in the organization.
- Actual content owners.
- Identities that must be mapped to Google Workspace.
Related content
- Files in SharePoint and OneDrive.
- Important links shared in channels.
- Bots, connectors, tabs and automations.
- Recordings or documents linked to meetings.
Recommended classification
- Migrate: active spaces, live projects, critical teams and channels with historical value.
- Archive: closed teams that must be retained for compliance but are not used in daily work.
- Do not migrate: duplicates, tests, unused channels or conversations with no operational value.
If no one knows who owns a Teams team, it is probably not a good idea to migrate it automatically. First you need to decide whether that content has value, who validates it and who will be responsible for the equivalent space in Google Chat.
3. Mapping Teams to Google Chat: teams, channels, spaces and users
In practice: mapping is where you decide what the user’s daily life will look like in Google Chat.
In Google’s native migration, Teams channels are imported as Google Chat spaces. This requires decisions: it is not always advisable to replicate the full Teams structure exactly as it is.
Common equivalents
| Microsoft Teams | Google Chat / Workspace | Practical comment |
|---|---|---|
| Team | Set of spaces or organizational collaboration unit | There is not always a 1:1 equivalent. Sometimes it is better to split or consolidate. |
| Channel | Google Chat space | This is the most direct equivalent for team conversations. |
| Team/channel owner | Space manager or administrator | This must be reviewed because roles do not always transfer identically. |
| Channel files | Google Drive / shared drives | Messages can be imported, but files require a separate strategy. |
| Tabs and apps | Google Chat apps, Drive, Docs, Meet or integrations | They are usually recreated, not migrated automatically. |
Naming best practices
Google Chat should be clear from day one. If Teams had unhelpful names such as “General”, “New project” or “Temporary team”, the migration is an opportunity to rename and simplify.
- Area — Topic: “Sales — Pipeline”, “IT — Internal support”.
- Project — Client: “Project Atlas — North Client”.
- Committee — Function: “Leadership — Weekly follow-up”.
4. Tools to migrate Teams to Google Chat
In practice: there are three approaches: Google’s native tool, the Google Chat API or specialized partners.
4.1 Google Workspace native tool
Google provides an option from the Admin console to import messages from Microsoft Teams to Google Chat. The process is based on connecting with a Microsoft administrator account, uploading a CSV with the Teams you want to import, mapping identities and running the import.
- Requires admin permissions in Google Workspace and Microsoft 365.
- Allows teams to be selected through a CSV.
- Allows user mapping through CSV when email addresses do not match.
- Allows an initial import and, before publishing the spaces, a delta import.
4.2 Google Chat API and import mode
For more customized scenarios, the Google Chat API lets you create spaces in import mode and insert messages through an authorized application. This approach requires development, permissions, API limit management and a more technical design.
It can make sense when there are special requirements: non-standard sources, message transformation, additional auditing, selective imports or needs not covered by the standard Admin console experience.
4.3 Third-party tools and partners
In large migrations or cases with complex requirements, solutions from specialized partners can be used. Google mentions migration and interoperability options for organizations that need more coverage, support or customization.
- Data migration partners: useful for migrations involving volume, reporting, traceability or transformation.
- Interoperability partners: useful when Teams and Google Chat must coexist for a period.
- Change management partners: useful when the main challenge is not technical, but adoption.
For small or medium environments, the native tool may be enough if the scope fits within its limits. For organizations with many teams, legal requirements, external users or a need for maximum traceability, it is worth evaluating a specialized tool or a hybrid approach.
5. What is migrated and what is not migrated natively
In practice: this section must be explained very clearly to the business to avoid unrealistic expectations.
What is usually migrated well
- Microsoft Teams channel messages.
- Channel name as a Google Chat space.
- Part of the text formatting: bold, italics, strikethrough, quotes, paragraphs and hyperlinks.
- Standard emojis.
- References to SharePoint links as links or visible names, depending on the case.
- Members and managers with certain conversion rules.
What is not migrated natively or requires special handling
- 1:1 chats between users.
- Non-channel group chats.
- Attachments as files uploaded from the computer or stored in OneDrive/SharePoint.
- Pasted images, stickers and some visual elements.
- Bot messages as fully functional content.
- Code snippets with their original formatting.
- Tables, complex lists, custom emojis or interactive cards.
- Messages from former employees or external users in certain scenarios.
- Very long threads, which may have limits on the number of imported replies.
“We are going to migrate the main workspaces and the useful channel history. Not every Teams element has an exact equivalent in Google Chat. The important content will be validated with each area and, if there is legal or critical content, it will be handled with a specific plan.”
6. Identity, users and licenses in Google Workspace
In practice: if identities are not mapped correctly, the migration may import messages but leave users with a confusing experience.
Before importing content from Teams to Google Chat, users must exist in Google Workspace, have an active license and have Google Chat enabled. In addition, source and destination email addresses must be mapped correctly.
Identity scenarios
- Same email: user in Microsoft and Google with the same address. This is the simplest case.
- Same user, different domain: for example, the name before the @ is kept, but the domain changes.
- Users with name changes: requires a source/destination mapping CSV.
- Former users: you need to decide whether to create accounts, preserve the name as text or archive the content outside Chat.
- External users: these must be handled very carefully because they are not always imported as equivalent members.
Source Email,Destination Email
ana.perez@microsoft-company.com,ana.perez@google-company.com
juan.garcia@microsoft-company.com,juan.garcia@google-company.comUser preparation checklist
- Users created in Google Workspace.
- Licenses assigned.
- Google Chat enabled for the required organizational units.
- Chat history defined according to company policy.
- Retention in Google Vault reviewed if applicable.
- Identity CSV validated before the pilot.
7. Teams files: SharePoint and OneDrive to Google Drive
In practice: message migration and file migration are two connected but separate projects.
In Microsoft Teams, channel files usually live in SharePoint, and files shared through chat are usually supported by OneDrive. In Google Workspace, the usual approach is to move team content to Google Drive shared drives and personal content to My Drive.
Key file decisions
- Which SharePoint libraries associated with Teams will be migrated to shared drives.
- Which links shared in Teams must be preserved, updated or documented.
- Which obsolete files should be archived instead of migrated.
- How permissions, owners and groups will be recreated.
- What to do with versions, metadata and very deep structures.
A Teams channel can migrate its messages to a Google Chat space, but its documents do not “magically appear” in Drive. If those documents are important, the corresponding SharePoint library must be migrated to a shared drive, permissions must be validated and a clear link must be left in the Google Chat space.

8. Security, retention and compliance in Google Chat
In practice: before importing data, you need to know how it will be retained, who will be able to see it and which policies will apply afterwards.
Google Vault and retention
If the organization uses retention or eDiscovery, it is advisable to align Google Vault rules before opening imported spaces. During import, spaces in import mode are treated in a special way; after completion, they become standard spaces and are managed with the usual policies.
DLP and sensitive data
If there was sensitive information in Teams, it is advisable to review DLP policies in Google Workspace and not simply “copy and move on”. The migration is an opportunity to better classify which spaces may contain customer data, finance data, human resources information or regulated information.
Chat history
Google recommends reviewing Chat history settings before importing. If history is disabled or there are conflicting policies by organizational unit, unexpected results may appear.
Questions security should answer
- Which migrated spaces must be retained?
- Which users can access historical content?
- Are there conversations subject to legal investigation or audit?
- Which DLP policies should apply after migration?
- Is it advisable to keep Teams in read-only mode for a period?
9. Step-by-step migration execution
In practice: the process must be repeatable, measurable and easy to explain.
9.1 Prepare Google Workspace
- Enable Google Chat for the organization or affected units.
- Review Chat history.
- Review Vault, retention and DLP.
- Create users and assign licenses.
- Prepare groups or organizational units if they will be used for governance.
9.2 Connect to Microsoft Teams
The native process requires connecting from the Google Admin console with an administrator account in Microsoft. It is important to do this with an account that is controlled, documented and approved by IT and security.
9.3 Create the CSV of Teams to import
The native tool allows you to select Teams through a CSV containing the team identifiers. Before preparing that CSV, it is advisable to filter: not everything should be imported.
Source MicrosoftTeamsID
8f445146-9d80-b020-d50d5589ab
bd4685f0-61f2-4789-4c1cda85d939.4 Upload identity mapping
If email addresses do not match between Microsoft and Google, a CSV is used to map source and destination users. This step must be tested in the pilot, because a mapping error can affect historical visibility.
9.5 Run the initial import
The initial import creates the spaces in import mode and copies the messages within the selected scope. While the space is in import mode, users do not access it.
9.6 Review reports
When the process finishes, reports must be reviewed: spaces created, errors, skipped items, warnings, unmapped users and channels not imported.
10. Validation, delta and go-live
In practice: Google Chat should not be opened to end users until spaces, members, messages and exceptions have been validated.
Technical validation
- Spaces created correctly.
- Messages imported within the expected range.
- Users mapped with no critical errors.
- Owners and members reviewed.
- Errors and warnings documented.
Business validation
Each area should review a sample of its spaces: name, members, key conversations and important links. It is not necessary to read the entire history, but it is necessary to validate that the important content is there and makes sense.
Delta import
Before publishing spaces, it is advisable to run a delta import to bring in new messages generated since the initial import. After deploying spaces to users, you should no longer rely on the same delta margin.
Space rollout
When validation is complete, the spaces are published for users. This is the moment when the change becomes visible, so it must be accompanied by communication, a quick guide and support.
11. Adoption: how to help users work in Google Chat
In practice: a migration can be technically correct and still fail if users do not understand the new model.
Messages worth explaining
- “Channels” are now “spaces”.
- Important documents will be in Drive, not necessarily inside the historical message.
- Not all Teams history is migrated, especially private chats and certain attachments.
- Google Chat integrates with Gmail, Drive, Calendar and Meet, so the workflow changes.
Role-based training
| Profile | What they need to learn | Recommended format |
|---|---|---|
| General user | Find spaces, reply to threads, share Drive files, start Meet calls | Quick guide and short session |
| Team owner | Manage members, pin resources, organize spaces | Hands-on workshop |
| Support / IT | Resolve questions, review permissions, interpret errors | Runbook and technical session |
| Management | Executive communication, announcement spaces, meetings | Personalized session |
Avoid saying “Teams disappears on Friday”. It is better to explain: “From now on, daily work continues in Google Chat; the main spaces are already prepared and you will have a guide to find what matters”.
12. Teams vs Google Chat: differences worth explaining
In practice: preparing users for the differences reduces frustration and support tickets.
| Aspect | Microsoft Teams | Google Chat | What to explain to users |
|---|---|---|---|
| Structure | Teams and channels | Spaces and conversations | There will not always be an exact 1:1 equivalent. |
| Files | SharePoint / OneDrive | Google Drive / shared drives | Documents live in Drive; Chat is the conversation layer. |
| Meetings | Teams Meetings | Google Meet | Meeting links and habits change. |
| History | Channels, chats, threads, bots, attachments | Partial import depending on support | Not all history will have the same format or availability. |
| Governance | Teams Admin Center / Purview | Admin Console / Vault / DLP | Policies are redesigned in Google Workspace. |
13. Operational checklists
In practice: checklists turn the migration into a repeatable and auditable process.
13.1 Before migration
- Google Chat enabled.
- Users created and licensed in Google Workspace.
- Chat history and Vault reviewed.
- Teams inventory cleaned up.
- Teams CSV validated.
- Identity CSV prepared if needed.
- Decision made about SharePoint/OneDrive files.
- Communication plan ready.
13.2 During migration
- Run the pilot.
- Review import reports.
- Fix unmapped users.
- Document items not imported.
- Validate spaces with business owners.
- Run delta before rollout.
13.3 After rollout
- Publish the user guide.
- Strengthen support during the first few days.
- Review issues by area.
- Confirm that Drive contains the relevant documents.
- Decide when to close Teams or leave it in read-only mode.
- Recertify permissions and external users.
14. KPIs and success criteria
In practice: measuring the migration helps separate a feeling of success from real success.
| Area | KPI | Indicative criterion |
|---|---|---|
| Import | Spaces created correctly | No critical errors in priority spaces |
| Identity | Users mapped | No key users left unmapped |
| Business | Validation by owners | Critical areas accept the result |
| Adoption | Google Chat usage after rollout | Real activity in migrated spaces |
| Support | Post-migration incidents | Downward trend after the first few days |
15. Common risks and mitigations
In practice: the biggest risk is not the tool failing, but migrating without clear expectations.
| Risk | Impact | Mitigation |
|---|---|---|
| Promising a complete migration of all Teams content | Frustration and loss of trust | Explain limits before the pilot |
| Not migrating related files | Messages without context | Parallel plan for SharePoint/OneDrive to Drive |
| Users mapped incorrectly | Confusing history or incorrect access | Validated identity CSV and pilot |
| Importing abandoned channels | Noise in Google Chat | Classification: migrate, archive or discard |
| Not preparing Vault/retention | Legal risk or loss of control | Compliance review before import |
| Not running delta before rollout | Recent messages are missing | Plan delta import before opening spaces |
| Lack of communication | Lost users and unnecessary tickets | Short guide, role-based sessions and initial support |
16. Frequently asked questions about migrating Teams to Google Chat
Can Microsoft Teams be migrated to Google Chat?
Yes. Google lets you import Microsoft Teams channel messages to Google Chat spaces from the Google Workspace Admin console. Even so, not all Teams elements have a direct equivalent, so it is advisable to run an assessment first.
Are Teams 1:1 chats migrated to Google Chat?
Not natively with Google’s standard import. 1:1 chats require an alternative strategy: preserving them as an archive, handling them through eDiscovery/export or analyzing specialized tools if there is a business or legal requirement.
Do Teams channels become Google Chat spaces?
Yes, in the native migration, Teams channels are imported as Google Chat spaces. Even so, it is recommended to review names, owners and members before opening them to users.
Are Teams files migrated?
Not as a complete part of the message in every case. Teams files usually live in SharePoint or OneDrive, so they must be migrated to Google Drive or shared drives through an independent file plan.
What happens to Teams bots, apps and tabs?
They are usually recreated or replaced. Bots, apps, approvals, connectors and tabs are not usually transferred as equivalent items to Google Chat. They need to be inventoried so you can decide what is kept, what is replaced and what is removed.
Can the migration be done in phases?
Yes. The recommended approach is to run a pilot, migrate in waves and execute a delta import before publishing the spaces. This reduces risk and allows errors to be corrected before the entire organization is affected.
How long does a Teams to Google Chat migration take?
It depends on the number of teams, channels, messages, users, related files and compliance requirements. The pilot is usually the best way to estimate real timings and adjust the plan.
Is it advisable to migrate the entire Teams history?
Not always. In many cases, it is better to migrate only active spaces and useful content, archive what is legally required and avoid moving noise. A well-designed migration improves the experience, not just moves data.
Can MSAdvance handle the entire migration?
Yes. MSAdvance can handle the assessment, target design, user mapping, message migration, related file migration, validation, communication and post-migration support.

18. Conclusion and next steps for migrating Teams to Google Chat
Migrating Teams to Google Chat can be a very positive transition if it is done realistically. Google’s native tool helps move channel conversations into spaces, but the success of the project depends on more than that: choosing what to migrate carefully, preparing identities, handling files, reviewing compliance and supporting users.
The recommended next steps are:
- Carry out a Teams assessment: teams, channels, users, activity and files.
- Define the target design in Google Chat and Google Drive.
- Run a pilot with a representative area.
- Validate results and limitations with the business.
- Plan waves, delta, rollout and support.
Why rely on a specialized partner
A specialized partner prevents the migration from becoming a succession of surprises: “this chat is missing”, “this file is not there”, “this user is not mapped”, “this space does not have the right owner”. The experience lies in anticipating those cases and explaining them before they affect the business.
