TeamsMigration

Migrate MS Teams meeting chat or group chat content to team channels, preserving sender attribution, timestamps, images, and attachments. Uses the teams-mcp MCP server for reading and the Microsoft Graph API directly for high-volume batch posting with automatic token refresh and rate limiting.

Workflow Routing

Workflow	Trigger	File
MigrateChat	"migrate chat", "copy chat to channel", "move messages"	`Workflows/MigrateChat.md`
ExportChat	"export chat", "backup chat", "download messages"	`Workflows/ExportChat.md`

Examples

Example 1: Migrate a meeting chat to a team channel

User: "Migrate the Teams meeting chat to the DevOps channel"
--> Invokes MigrateChat workflow
--> Verifies auth, fetches all messages with pagination
--> Filters system/deleted messages, reverses to chronological order
--> Posts each message with sender + timestamp attribution
--> Verifies count parity and spot-checks content

Example 2: Export chat messages to a local file

User: "Export all messages from our DevOps chat"
--> Invokes ExportChat workflow
--> Fetches all messages with full pagination
--> Saves to JSON file with metadata

Quick Reference

MCP Server: @floriscornel/teams-mcp (npm)
Auth file: ~/.msgraph-mcp-auth.json
Token cache: ~/.teams-mcp-token-cache.json
Auth command: npx @floriscornel/teams-mcp@latest authenticate
Migration tool: Tools/MigrateChat.mjs (Node.js, no dependencies)

Key Learnings

Graph API descending: false not supported -- fetch descending, reverse array
download_message_hosted_content only works for channel messages, not chat messages
Token auto-refresh via MSAL refresh token in ~/.teams-mcp-token-cache.json
Rate limiting handled by respecting Retry-After header on 429 responses
For bulk posting (50+ messages) use Tools/MigrateChat.mjs directly via Graph API instead of MCP tool calls
Account must have Teams license -- Chat.* endpoints fail without it (403)
