How is a recommended process to migrate from a Wireless C25 HA pair to a single V2110

[Marcus_Mathuni_]

Hi community,
I want to know how to migrate from a C25 HA pair (V8.32) to a single V2110 (V9.21) seamlessly or by minimal interrupts for Wireless services.
Which minimum firmware at C25 is required to migrate the configuration to V2110 V9.21 firmware ?

Thank you in advance.

you can upgrade the C25 to V9 and it will have a 7day grace period. With that said, you can export the config and roll the controllers back with the rescue image.

Just set the AP's for a controlled upgrade so that it does not affect the connected clients (unless they are B@EWC
