Upgrade from 9.3.0 to 10.0 questions
I have two LTM 1500's running version 9.3.0 and I'm ready to upgrade to 10.0. I'm running Active/Standby so I presume it should work like this:
1. Upgrade the standby unit to 10.0, verify it's working properly
2. Failover to the newly upgraded unit
3. Upgrade the original active unit which is now standby
Will I have any issues with failing over from the Active unit which will be running 9.3.0 to the Standby which will be running 10.0 after the upgrade? We are running HA with network failover as well as having the serial cables directly attached.
I've found some posts stating you can't failover units running different versions of code so I want to make sure this is the correct procedure. Thanks in advance!
