Hi Robert,
What you wrote sounds very much like one of the four VMware KB articles that I made reference to in my post. As I mentioned at the top of my post, my procedure is heavily based on a number of VMware KBs I used. I collated all the important things from the KBs in putting together my step-by-step guide. I recommend anyone wanting to follow my guide to read all KBs I made references to and then follow my guide. My guide includes tips & tricks that are not mentioned in the KBs. For example, my step No 7 says "On vc5, stop and restart the vCenter SQL Database service, then insert the vCenter 5.5 DVD and get it to do a fresh install. Do not select the Simple Install option. Install each component one at a time..". This tip isn't mentioned in any of the KBs. Also, my steps 11 to 13 aren't mentioned in any of the VMware KBs.
Many thanks,
George.
