From the code compare, we can see the boot/snapper_rollback.pm has more debug info before and after rollback, while from the main purpose for rollback test they are the same almost.

I have checked about 10 online migration test cases, all with ONLINE_MIGRATION=1 and UPGRADE=1 together but no issue found.
So I suggest to use the boot/snapper_rollback by set ROLLBACK_AFTER_MIGRATION=1 for online/offline migration test cases.

We already in the same page after discussion in team, just use the boot/snapper_rollback by set ROLLBACK_AFTER_MIGRATION=1 for online/offline migration test cases.
