I can't for the life of me find an answer but I thought there was some extra "notes" for upgrading two 5508 controllers in a mobility group. I have about 150 AP's (1140 series) and would really like to minimize the downtime as much as possible. My current plan is as follows:
Upgrade WLC-2 (the secondary)
Reboot WLC-2
Upgrade WLC-1 (Primary w/all the AP's attached)
Push the AP image {predownload primary all}
Wait for the push to finish
Reboot WLC-1
Any tech notes / real life lessons learned you can share would be great. It's a Hospital so I need to keep the downtime to an absolute minimum.
Going from 7.0.116 to 7.4.110
Thanks,
Todd

As long as you will not be going to implement HA SSO, 7.4.110.0 seems to be a good version. Although I haven't used this, some people have had good results with this version.
Your upgrade process is OK.

I was actually looking at HA to keep the configs in sync. Are there problems with it?

Not really.
I'm using 7.5 and I don't see any issues.
Have done multiple failovers of the AP during business hours and no one seemed to notice.
