Thanks for your response.
I've been to that article, I'm interested in what it calls "method II*, but it doesn't show any instructions for it. I did follow the link on that page that showed the steps for version 4.x, but it seemed to have no effect. Are there step-by-step instructions do move a single client to a new primary server for version 5.x or are the instructions for version 4.x supposed to work?
