iOS update using MDM

Question

Ive been reading so much doco and havent been able to find the answer, so posting here seems to be next option. 
 
 How do I update iOS using Sophos MDM? specifically: 
 1. "force" the device to update now (dont care if wifi or 4G) 
 2. Make the device update using wifi only when available 
 3. And also, block (stop) iOS the update. 
 
 Thank you in advance 
 Pete

Hi Peter Smith3 
 This link should help you out pushing the latest iOS updates. This link should help you out in blocking over-the-air PKI updates and delaying iOS software update. AFAIK, Apple does not support updating over cellular data, but if you still wish to see this feature in Sophos Mobile, I would request you to raise a feature request .
