Migration Process
What Happens After Consent
- • DM messages are extracted into HTML files organized per conversation
- • Files are uploaded to a "Slack" folder in the user's OneDrive
- • Only the 1000 most recent messages are injected into Teams chats
- • Older messages are stored in HTML files for reference
Technical Limitations
Important Notes
- • Message Attribution: Messages appear in Teams chats created by the migration account (Microsoft API limitation)
- • Timestamps: Each message displays the original creator and date in the body, but system timestamp reflects migration date
- • Message Limit: Only 1000 most recent messages per conversation are injected into chats
- • Cleanup: The migration account is removed from chats after completion
User Consent Required
Without individual user consent, direct messages cannot be migrated. Ensure
clear communication to users about the consent process.
