citizen_elah , Thank you for your advise.
I don't have a test environment, the 2 BIG-IP systems ( HA pair) are in a production environment.
So I will have to do the upgrade on live.
But I have another question, a more general about upgrading HA pair from 9.1.X to 9.3.x.
This is how I want to proceed ;
1. Upgrade the standby unit and failover to it.
(9.1.2 --> 9.3.1 + HF1 ).
2.upgraded unit becomes Active unit.
so after the above actions, i have the below setting :
active unit ( version 9.3.1 + HF1) and standy unit ( version 9.1.2 ).
I plan to keep the above configuration for about 1 week, then if there are problems, I failover to standy unit which is still version 9.1.2.
HA configuration(active-standby) with 2 differents versions of BIG-IP will work fine ??
Active ( 9.3.1 ) and Standby ( 9.1.2) HA is possible ??
thank you.
Sako.
