I am not enough understood what do you want. you want to move all cluster( all IAP), or only slave IAP?
condition 1: move cluster(master IAP(VC) + all slave IAPs)
if you can factory reset VC
1 factory reset your old VC
2 old VC get new netwrok profile
3 old VC get airwave information
4 delete all date at old group
5 add old VC to new group, get new config.
6 other slave IAP get new network profile, form cluster.
7 add other IAP to new group.
If can't factory reset.
1 old cluster get new network profile
2 move to new group at airwave. Method: at monitor page of old group, click " modify devce" button, select you want to move device, select new group and folder, click "move".
3 airwave will push new config to old VC, you need deal with mismatched item.
condition 2: move slave IAP
1 IAP get new profile , add to new cluster, this cluster have added to new group.
2 move iap from old group to new group, method same above step 2.
3 that's all.
