Microsoft Teams tenant-to-tenant migrations are very challenging to plan, but we’ll cover guidelines to make it easier, including solid plans to help you:
a. Where is all the content stored
b. How much content is there
2. Prepare the target tenant ahead of the migration
3. Set expectations ahead of time, including:
a. What can and cannot be migrated
b. How long will it take to migrate
c. When to stop incremental migration
4. Prepare a communication plan (brief)
5. Create a migration plan (brief)
a. What order should content be migrated in?
b. Should Teams be migrated individually or migrate the content type (SharePoint, conversations, Planner, membership) in each Team together?
c. How do you coordinate Teams migrations with other workloads?
d. What if users are working in both source and target tenants?
6. Post migration validation
7. What about Teams settings that cannot be migrated with migration tools?
