Migrating and renaming a group does not create a new group, it merges into existing group (4351489)

GroupA has been migrated to the target domain, SID History and Extension Attributes in target are being populated.

Now the goal is to migrate GroupA again, but this time using a renaming (import file) and create a new GroupB in target domain.

Matching attributes have been cleaned up (deleted).

Import file is configured correctly, syntax is:
samaccountname samaccountname name
GroupA GroupB GroupB

but it still merges into existing GroupA, it creates GroupB but GroupA disappears (is renamed)

It has been confirmed that this happens because the group has been migrated with sid history.

Possible workarounds:

1. Use Active Directory Processing Wizard to remove (clean up) SID History.

2. After cleaning up matching attributes unselect the option "Match by SID History" under domain pair properties, this  allows to perform the task described above.
