Affected processes:
Core verification processes:

VerifyPermission

We will keep the following rules in mind:

In case we can not remove certain parts of the logic we should move them as upgrade processes.
We can keep some of the process to verify data but not to modify it.
(Since we just support dirtect upgrades from 6.1 and highier to 7.1, all the code added in verifiers for 6.1.1 or below, could be removed since the database already has passed throught it)
