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 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 source and destination administrators for the duration of the migration.
