Moved to ePO for better handling.
After I have read the installation documentation of 5.1 I came to the conclusion to leave the OS with 2012 and just to the upgrade from 5.0 to 5.1.1 as an in-place upgrade.
If there is someone out there that has some experience with it please let me know, so I'm not getting into traps out there.
Easiest method would be along the lines of below:
You could snapshot the entire VM, then create a new VM based on the snapshot; do the OS upgrade, then ePO upgrade as a test.. if all works just update the old DNS record to point to the new server. Otherwise just continue working how you are and do the ePO in place upgrade.
From McAfee: The Agent uses either the last known IP address, DNS name, or NetBIOS name of the ePO server. If you change any one of these, ensure that the Agents have a way to locate the server. The easiest way to do this is to retain the existing DNS record and change it to point to the new IP address of the ePO server. After the Agent is able to successfully connect to the ePO server, it downloads an updated SiteList.xml with the current information.
I'll give it a try, but may take some day's to get the change approved first. Once done I'll post the results.
Hi ahamm what is the result of your upgrade? And only epo or also Windows 2012 to R2?
