Changing licensing level in 9800 HA SSO deployment

Level 1

Hi Guys!

Freshly deployed wireless system gone into production 2 months ago. We have 2 piece of 9800 WLCs in HA SSO deployment model. Unfortunately the licensing level was not set on startup, now I would like to set it up. As I know, after changing licensing level, box(es) should be reboot.

My question is: in a HA deployment, is it possible to change licensing level and reboot controllers without clients experiences any disruption, or not?

Thanks!

I have not tried that either but before trying a reboot you could try "redundancy force-switchover", wait for them to come into sync again and then "redundancy force-switchover" again.  That way there should be minimal/zero impact to clients and it might get the license fully updated (because each chassis reboots when you do the switchover). 

If that doesn't work then you'll have to plan a full reboot.

I haven't done this before, but I guess you might have to reboot the controllers.

It worked, thank you!
