There is a couple of devices that connected to the new server but all have been rebuilt.<br />
<br />
We are looking at keeping the new server and manually rebuilding all the collections, packages etc as there is only about a 100 to do and we want to new server to be clean as possible and the old one is failing.<br />
<br />
I have removed the Management point DNS record and no more devices are connecting at the present time. We are setting out PKI and all communication to the new server will be secure. So I believe we should be able to have both systems as the old only is setup for http and the new is https only.
