Just upgraded Primary server, have a question
So I upgraded the failover (now 2.3) server on Friday and everything got synced from the primary (was 2.2.x) and now it's handling all the traffic while the Primary is in maintenance.
The Primary firewall has now been upgraded with a clean install. When I initiate HA, will the current data from the failover sync over to the primary? Or will the primary force to sync its current state (completely empty) to the failover.
I do have backups, but I'd like to sync as a form of restoration to the primary this time around.
