Map the default groups in SharePoint

Right now you can map AD users/groups manually through a CSV but it doesn't apply to SharePoint groups.

The problem comes with default groups when migrating to a site collection already created at the destination. At the end of the migration, 6 default groups are available: the 3 source groups and the 3 destination groups.

The problem is even greater if we want to keep the permissions since the tool breaks inheritance in all the lists/libraries due to
The source Visitors group is different from the destination Visitors group
The source group of Members is different from the target group of Members
The source Owners group is different from the target Owners group
