Is Zero Downtime Migration Really Possible During Microsoft Teams Migration?
The term "zero downtime" in tenant transition looks more than promising, but it can slightly mislead you. Due to tenant-level misconfiguration, zero downtime is difficult. However, organizations can make migration up to zero downtime, and end users can continue their work during the migration process in progress in the background. For that, admins should:
Migrate data in multiple stages.
Sync all Teams data before the cutover process.
Schedule final transitions during off-hours or weekends to keep the workflow unaffected.
If these strategies are followed, there is a high chance that users may not even notice most of the migration process.

When looking to migrate Microsoft Teams between tenants with no planning, organizations face:
Missing conversations
Inaccessible files
Permission conflicts
User confusion
Extended service interruptions

Channel structures and metadata
File accessibility levels
Accuracy in chat data.

Changes they see
Migration timing
Expected impacts
