Sharegate displays the following error :
Microsoft 365 was unable to create the Microsoft Azure migration job.
You get this error when you migrate to Microsoft 365 in Insane mode, and the job creation in Azure fails.
This usually happens when the Microsoft migration API behaves incorrectly.
If you retry the migration and the issue persists, you might have to contact Microsoft's support to investigate it. To improve the resolution effectiveness:
- Confirm if you get the same error when migrating to another site collection.
- Confirm if you get the same error when migrating to another library in the same site collection.
To better understand how ShareGate's migration tool works with the migration API, see SharePoint to SharePoint migration diagram.
