Active and Passive LTM pairs. Moving between prod1 and prod2

My company wants an active ltm pair where traffic is flowing, and a passive ltm pair (where the devs are changing and preparing the environment, prod1 and prod2. On changeover day, we switch from active to passive where the new, tested servers are. They want to have a third ltm pair above active and passive where we make the switch. What's the best way to do that? One pool with two nodes (active and passive) and priority groups? when we make the change, just change priority so it goes to the p2 ltm's? if so, will that kill current connections or will it bleed over? Maybe an Irule change is better? Maybe disable and enable nodes?

  • For the prod1 and prod2 parts, there are multiple ways to do that. I would just setup 2 virtual servers and 2 pools. One virtual server is production, and the other test. One pool represents prod1, and the other prod2. When they want to switch environments, just point production virtual server to pool prod2. Only new connections will be affected, so new connections will start to go to pool prod2.

     

    Can you explain the number of HA pairs you will use? Also, what function they will have, as I can't understand why you need 3 pairs.
