When you use the data migration service, you can adjust the migration speed. The migration speed sets the number of simultaneous requests being migrated at a time.
Important: You cannot change the migration speed when migrating data from Google Workspace or Gmail. These migrations are always set to unlimited concurrent users as the maximum speed.
You must be signed in as a super administrator for this task.
Adjust the migration speed
Recommendations
- Set the migration speed to half the number of users you're migrating. For example, if you're migrating 100 users, set the migration speed to 50.
- Otherwise, leave the migration speed at the default value, which is 100.
- Don't select a migration speed that's larger than half the number of simultaneous requests your source server can handle. Doing so can put too much load on your legacy mail server.
