migration of C4110-2 and AP3620 to Hardware Controller C5210 and AP3935i...

[Taylor_Durden]

Hello Community,

we have to do a smooth migration with Hardware Controller C4110-2 Firmware Version 9.21.01 and Access Points AP3620 in a Failover cluster to Hardware Controller C5210 and Access Points AP3935i.

Has someone experience with such kind of migration? Is it just an configuration export and import job?

Thank you in advance.

best regards
Ben

Hi,

you can take every rescue image 9.x.x. with the certain Controller type.
You need this in order to get down to v9.xx and than you can downgrade or upgrade like always.

Rescue image will have also the config .
If it's not your rescue image you need set the controller to factory default before you maybe start to re-build the config.

After this you need install your saved config on to this controller.

Hi Ben,

Are you downgrading firmware from V10 to V9?

Okay, i have an update for you.
We have received our controllers and we tried to downgrade the firmware...with the following result:

Error: Cannot upgrade with AC-MV-09.21.16.0013-1.rue
Output:

What we have to do now?
