Upgrading 4200 from BIG IP 11.5.4 to 12.x
I currently have a 4200 with following modules LTM, APM and ASM running on 11.5.4 code. We would like to go the 12.x code. What is the best practice do this code upgrade? Our DMZ F5's are configured with the virtual's pool member as the virtuals on the inside F5. This was configured as a security measure is my understanding. I was thinking of upgrading one F5 at a time in the HA pair a night and give it a 24 hr period to see if the applications behave. I think one would need to upgrade an the DMZ F5 and the Internal F5 one device each per HA the same night. In case there is an issue with the apps we can failover to the redundant box running on code 11.
