I'm about to upgrade the code on 2 WiSM WLC's from 4.2.130 to 4.2.176 and then to 6.0.182. Then move these 2 WLC's to a new mobility group which will be created as well. After creating the mobility groups, I plan on moving ONLY 4 -1130's from an existing mobility group over to the new mobility group.
Q1 - Is it best practice to have the 1130 LWAPP AP's join the 4.2.176 prior to joining the 6.0.182 or does it really matter?
Q2 - Also, should I attach the 1130's to the upgraded controllers prior to creating the new mobility goups or after ?
Q3 - Lastly, are there any caveats from downgrading an 1130 LWAPP AP from 6.0.182 back to 4.2.130?
