Collaboration Migration: Google Chat, Meet, and Spaces to Microsoft Teams¶

Status: Authored 2026-04-30 Audience: M365 administrators, change management leads, and IT teams managing the transition from Google collaboration tools to Microsoft Teams. Scope: Google Chat to Teams chat, Google Spaces to Teams channels, Google Meet to Teams meetings, Google Groups to M365 Groups, and Google Voice to Teams Phone.

Overview¶

Unlike email and Drive, Google Chat/Meet/Spaces data generally does not migrate to Microsoft Teams through automated tools. Chat history, Space conversations, and Meet recordings are platform-specific. The migration is primarily a workflow transition supported by user training, communication, and change management.

Key principle: Plan the Teams structure before the transition. Map Google Spaces to Teams channels, create the channel architecture, and deploy Teams to users before the Google Workspace cutover date.

Google Chat to Microsoft Teams chat¶

What migrates¶

Chat history from Google Chat does not migrate to Teams. This is a platform limitation, not a tooling gap. Google Chat messages are stored in Google's infrastructure and are not exportable in a format Teams can ingest at scale.

Migration strategy¶

1. Archive Google Chat history via Google Vault export before decommission.
2. Communicate the cutover date --- all new chat conversations start in Teams after date X.
3. Deploy Teams to all users 2-4 weeks before the chat cutover date.
4. Enable side-by-side usage during the coexistence period so users become familiar with Teams chat.

Google Spaces to Microsoft Teams channels¶

Mapping strategy¶

Google Spaces are persistent conversation areas organized around topics, projects, or teams. They map to Microsoft Teams channels.

Creating the Teams structure¶

Step 1: Inventory Google Spaces¶

Document all active Google Spaces:

• Space name and description.
• Member count and membership list.
• Activity level (messages per week).
• Purpose (team communication, project coordination, announcements).
• External members (if any).

Step 2: Design the Teams architecture¶

Map Google Spaces to Teams:

Step 3: Create Teams and channels¶

# Connect to Microsoft Teams
Connect-MicrosoftTeams

# Create a team
New-Team -DisplayName "Engineering" `
    -Description "Engineering team collaboration" `
    -Visibility Private

# Get team GroupId for adding channels
$team = Get-Team -DisplayName "Engineering"

# Add channels
New-TeamChannel -GroupId $team.GroupId `
    -DisplayName "Frontend" `
    -Description "Frontend team discussions"

New-TeamChannel -GroupId $team.GroupId `
    -DisplayName "Backend" `
    -Description "Backend team discussions"

# Add members
Add-TeamUser -GroupId $team.GroupId `
    -User "developer@contoso.com" `
    -Role Member

# Add owners
Add-TeamUser -GroupId $team.GroupId `
    -User "lead@contoso.com" `
    -Role Owner

Step 4: Configure channel settings¶

# Enable moderation on announcement channels
Set-TeamChannel -GroupId $team.GroupId `
    -CurrentDisplayName "Announcements" `
    -ModerationSettings @{
        AllowUserToPostMessages = $false
        AllowUserToReplyToMessages = $true
    }

Google Meet to Microsoft Teams meetings¶

What migrates¶

Google Meet meeting history and recordings do not migrate to Teams. The migration is a workflow transition.

Feature comparison¶

Teams meeting deployment¶

1. Configure Teams meeting policies in Teams Admin Center.
2. Deploy Teams desktop and mobile apps via Intune.
3. Train users on Teams meeting scheduling, recording, and Copilot features.
4. Configure meeting room devices (if replacing Google Meet hardware).

# Configure Teams meeting policy
Set-CsTeamsMeetingPolicy -Identity "Global" `
    -AllowMeetingRecording $true `
    -AllowTranscription $true `
    -AllowCartCaptionsScheduling "EnabledUserOverride" `
    -MeetingChatEnabledType "Enabled" `
    -AllowMeetingReactions $true

Google Groups to M365 Groups¶

Google Groups types and M365 equivalents¶

Migration steps¶

Step 1: Export Google Groups¶

Google Admin Console > Directory > Groups

Export:

• Group name and email address.
• Member list with roles (owner, manager, member).
• Group type (distribution, collaborative inbox, announcement).
• Access settings (who can post, who can view).
• Number of members.

Step 2: Create M365 Groups or distribution groups¶

# Create an Exchange distribution group (for email-only distribution)
New-DistributionGroup -Name "All Engineering" `
    -PrimarySmtpAddress "engineering@contoso.com" `
    -Type Distribution

# Add members
Add-DistributionGroupMember -Identity "engineering@contoso.com" `
    -Member "dev1@contoso.com"

# Create an M365 Group (for collaboration: shared mailbox + SharePoint + Teams)
New-UnifiedGroup -DisplayName "Project Alpha" `
    -PrimarySmtpAddress "project-alpha@contoso.com" `
    -AccessType Private

# Add members
Add-UnifiedGroupLinks -Identity "project-alpha@contoso.com" `
    -LinkType Members `
    -Links "user1@contoso.com","user2@contoso.com"

Step 3: Configure group settings¶

# Restrict who can send to a distribution group (announcement-only)
Set-DistributionGroup -Identity "announcements@contoso.com" `
    -AcceptMessagesOnlyFrom "ceo@contoso.com","comms@contoso.com"

# Configure M365 Group expiration policy (via Entra ID)
# Configured in Entra Admin Center > Groups > Expiration

Google Voice to Teams Phone¶

Overview¶

Google Voice provides cloud-based phone service in limited markets. Microsoft Teams Phone provides enterprise-grade cloud PBX with broader capabilities and availability.

Migration considerations¶

Teams Phone deployment options¶

# Assign Teams Phone license and calling plan
Set-CsPhoneNumberAssignment -Identity "user@contoso.com" `
    -PhoneNumber "+12065551234" `
    -PhoneNumberType CallingPlan

# Configure auto attendant
New-CsAutoAttendant -Name "Main Line" `
    -DefaultCallFlow $defaultCallFlow `
    -TimeZoneId "Pacific Standard Time" `
    -LanguageId "en-US"

Communication plan for collaboration migration¶

Timeline communication¶

Training topics¶

1. Teams basics: Chat, channels, mentions, notifications.
2. Teams meetings: Scheduling, recording, transcription, Copilot recap.
3. Teams files: Accessing OneDrive and SharePoint files within Teams.
4. Teams apps: Using Power Automate, Forms, Planner within Teams.
5. Teams Phone: Making and receiving calls (if applicable).
6. Teams mobile: Using Teams on iOS/Android.
