what is the correct Rollback procedure of f5 HA upgrade

[Sarovani]

Hi Team ,

If we are upgrading HA pair , and say we have completed the upgrade on both the devices from version 15 to 16 and after some time application team reports an issue and we have to rollback the changes on both the device then what will be the step by step procedure .

We have to start the rollback from which device first ?

-Rollback standby device BIGIP-2 (version 16 to 15 )

-Failover from Active device BIGIP-1 (v16) to standby device BIGIP-2 ( v15)

-Rollback BIGIP-1 ( version 16 to 15 )

As you have said, rollback the standby, failover and rollback the newly standby

Hello, I'd like to add that any configuration issued after the upgrade won't be found when you rollback. Also, "Install configuration" option won't be available because newer software options might not be compatible with old version, so you'll need to replicate any change manually once cluster is downgraded.

Basically you're activating the partition with configuration up to upgrade day, so it will be like "reverting" config to that day.

What all commands I need to run after the upgrade to know the upgrade is 100% successful ?

They very much depend on your environment.
