Config sync after the upgrdation

Hi,

 

I am planning to upgrade the my F5 OS version from 11.2.1 to 11.6.1. We have two systems and they are in the HA state. Just need to ask that after upgrading the both systems to the same version does the both systems are automatically goes in the HA state ?? or we have to configure again the HA configurations.?

 

Waiting for the response. thanks.

    They should keep the HA config. Upgrade standby first but don't sync the config, fail over to standby, test and then upgrade the other one fallback, test and sync . You may just need to rebuild the trust.
