Are the AP's 'managed' on the new XIQ system? That might be all that is required! This however is assuming the policies, templates, user profiles previously configured on the 'old' XIQ have effectively been copied/configured on the new XIQ instance? OR the policies on the new XIQ system will continue to provide users the same access as they do already. Personally I would contact GTAC and ask exactly what they did and what is required to bring them online in the new instance and ask the question about policies, user PPSK keys etc?
