Error Message: "One or more errors occurred. => The operation has timed out"
Description: The MigrationWiz servers are not able to connect to the tenant due to enhanced security. This prevents them from auto-discovering the users.
Cause: The Microsoft security-enhanced tenants block some of our features. While we are working on a solution, it is still in development. At this time, we do not support enhanced security tenant migrations.
Resolution: The enhanced security can be temporarily turned off for the entire tenant for the duration of the migration.
