Here's a tricky one.

NimbostratusThe requirement is for both pools to be active, one in development the other live. They then flip the pools to a new release, which allows the immediate rollback in the case of a bug.
It also removes the requirement for the Devs to get in touch with the F5 admins.
I will have two VIPs. One for live and one for dev. They will have exactly opposite rules. Meaning that the Live VIP will point to the stable active pool. And the dev VIP will point to the new release pool.
When the toggle is initiated, leg A or leg B both VIPs change target pool.
The logic would be:
VIP Live
if response = legA
then use pool A
if response = lebB
then use pool B
VIP Dev
if response = legA
then use pool B
if response = legB
then use pool A
Additional reponse options may be
if response = main
then use pool C (and pool C is a maintenance page)
