I'm looking into using MWG7.2 but one of our requirements is that it must be able to be updated without it connecting to the internet. Ideally having ePO push out updates or failing that pointing MWG to an internal location for it's updates.
Is there a way of updating it without it contacing internet servers?
there is no direct way to do this.
In case you devices don't have internet connectivity, you can still install one instance internet facing and make that part of the update group and disable internet updates on the others.
