Hi @Stefanos Evangelou ,
Per my understanding, here is a checklist for you:
- Check whether the SharePoint version and the system requirements meet demands in the reference:
https://learn.microsoft.com/en-us/sharepointmigration/overview-spmt-ps-cmdlets - Would you like to share the script? It will help us troubleshoot more accurately. The new PowerShell cmdlets support three different types of migration tasks, you can test with another type of task and see if it works.
- If you have confirmed that the permission is fine, please check if there are any other error messages in the Tool Log. If yes, here is a simple reference for troubleshooting:
