Access Point Firmware

Hey guys, I think I know the answer but need confirmation
we have 2 wireless controllers. One is a failover to the other. I upgraded Controller 1 from V9 to V10 and upgraded the AP's.
Controller 2 is still on the old V9 code. The upgraded AP's no longer see controller 2 as a backup tunnel. Is it because of the firmware difference?

As I understand it you are correct.
Awesome, I upgraded the 2nd controller today and noticed backup tunnel from controller 1 AP's were re-established to controller 2. Thanks!
