Hello Yusuf,

Is it giving you an error? or failing during the synchronization?

Image differences ... you can't have one running 12.5 and the backup running 16.2.

You will need to downgrade B or update A.

To downgrade B to A's image you could force a sync. This should be not effect network and be non-impacting. A will copy it's primary and secondary images over to B and B will reboot and come back up synced. It would be better to upgrade to current code but you would have to have a system reboot for that due to code differences

Thank you
Yusuf

And
- What if I did a , would I be able to run on B slot and upgrade A slot later?

- Is there any way to sync A from B?

you will need a valid support contract to access the downloading of images... You will need to call TAC if you do not have a contract and this is a new card to see what options you may have.
