what is the correct Rollback procedure of f5 HA upgrade

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.
