SharePoint migration tool and Active Directory Groups

We have a department that is looking to migrate from a file server to SharePoint Online. In looking at the SharePoint migration Tool, I know this is possible, but I have a question regarding permissions.

 

Most of the permissions on the file server shares are set to groups in our local AD. Most, but not all, of those groups are synced to Azure AD. Assuming the groups are synced, do we need to generate a custom mapping file, or will the Migration Tool assign permissions in SharePoint to the same AD group that's used for the file server share? 

 

Likewise, if all user accounts are synced to AAD, do we need to still create a custom mapping file?

    Hello,

     

    If you decide to preserve user permissions, the permissions on the target library will be replaced by that in source root folder. Existing files -in destination- with Unique permissions won't be changed. Migrated files without any permission in the source will have inherited permissions and inherited role assignments from the target library. Migrated files with any permissions in the source will carry over these permissions as unique.

     

    There could be multiple behaviors depending on the parameters used for the migration, and the destination (root folder, subfolder, etc.). I'll ask you to take a look at this article for additional information: https://docs.microsoft.com/en-us/sharepointmigration/understanding-permissions-when-migrating.

     

    Have fun!
