I am about to do a migration introducing a brand new server. there is one thing in MS white papers that is bothering me, about front end servers. It says that 'all front end servers have to be upgraded first'. This is my dilemna. I am replacing my mail server with a new box, and then shifting that old mail server to be my new web server (also a front end exchange box). I can only upgrade my front end server after the back end one has been upgraded, giving me the extra server to replace. The only thing I can think of is uninstalling Exchange 2k from the front end box the day before the upgrade... but this would give us no web mail for at least 1 whole business day. Plus I would be constricted to installing E2003 on that same day ( a friday...and doing all the server replacements on the weekend). I wanted to get exchange installed/tweaked a few days ahead of time, so that I was sure that all public folders and such have replicated. any tips would be greatly appreciated. -Jason
