I would like to know the best practice/method for upgrading an active/active print cluster from Windows 2003 Server SP1 to SP2. What implications (if any), the best method for upgrading the individual servers, etc.? Would there be any possible issues that could arise if one is upgraded without the other such as a scenario where one would want to update one of the nodes one week and another the next week? The two servers are sharing resources. I don't know why the two servers were set up as active/active sharing the same resources but I've been told that one server couldn't handle the high number of print jobs.
