In Newyork Version instance after performing clone , users are not able to login in target instance using Multi factor authentication(MFA)
Table 'user_multifactor_auth' from source Instance is being copied over to target Instance when the clone finishes. This must be preventing the users from logging into the target instance using MFA. In target after the clone it could be having source values & Multi Factor secret value is incorrect which could be causing the issue .
Manually add the table 'user_multifactor_auth' in Clone exclude table in the source instance before performing the clone . Alternatively, you can also export the records from the table as XML before cloning and then after cloning import the XML into the target instance but this import XML activity can only be achieved when the local admin user is able to login to the target instance post the clone.
