So, I tried to upgrade to SU4 and it failed miserably .. TAC took a bunch of reports and came back with "Try to run it from the CLI" which is what I did in the frist place, so I'm not sure how much help they're going to be.
In every search for the below error message indivduals say to switch versions using the recovery CD, however I can't seem to find any documentation detailing how to do that.
Can someone send me the "how to" or if you've had the same thing happen, please let me know what you did to fix it.
I am assuming that you have initiated the Switch version only on the UCCX first node (Publisher) , once the switch over of this pulisher is complete than only you have started the switch version on the Second Node (subscriber).
Also please refer the detailed procedure for this process in the section "Software Upgrade Procedures" from page 52 onwards in the below link,
My guy at TAC says no to the remore support account thing .. wants me to boot from recovery CD and choose option "S" to switch versions. Does anyone have some screen shots of what this looks like? When do I get to "choose options S"?

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
