With the release of XenServer 5.6 Feature Pack 1 it was due time to upgrade my Homelab to the latest version. So eagerly I started to burn the downloaded iso files for the install and linux supplement pack CDs and burned the ISO files to CDs. With a quick scan through the Admin Guide, I figured I understood the process and made my first mistake.
I performed the upgrade in the wrong order, so had to do some troubleshooting.
