SharePoint Migration Tool - Full Control permission not preserved

Question

I'm using SPMT version 3.2.118.0 and I'm trying to migrate a folder of a file share to the root folder a doclib of a SPO site while preserving permissions. Groups or users with Read and Write permissions are well migrated with these permissions preserved (read--read, write-->contribute) but groups or users with "full control" permissions are not migrated at all! And SPMT reports it has successfully migrated the content!

Example:

If my local share is C:\TestDocs with

• user1 having Full control
• group1 having Read perm
• group2 having Write perm
• group3 having Full control

The target /TestDocs document library of the SPO site will have indeed unique permissions but with:

• group1 having Read perm,
• group2 having Contribute perm

user1 and group3, which were supposed to have Full control permission, don't have any and have zero access to the doclib!

I checked the reports and logs but cannot find any information.

Any idea?

Thanks

Franck, make sure you have synced the corresponding users and groups to Azure Active Directly before you do the migration.

According to the document: File and folder permissions when using the SharePoint Migration Tool:

Read, Write, and Full control permissions will be migrated as long as users are mapped between on-premises and SPO. Write permission will be set to Contribute after migration while the other two will be reserved.

These are expected behaviors when using SPMT.

Just sync Active Directory accounts to AAD and run the tool again.
