Ok, this is just an update. We successfully got Wndows3 to run on the new server hardware.. now the fun stuff begins. Originally we were going to let windows3 run on its own... but for some reason the old windows3 just decided to die, so what we are going to do is put the new one online.. but we will be running upgrades on it which will take sites down. Between each upgrade, we will verify that web sites and email are working, and then shut it down, make a backup at that point in time, and start up again to do the next upgrade. This is going to be a long process, and it sucks that Plesk requires us to do 3 upgrades to get to the latest version, but once we are there, you guys will be very happy.
Anyhow, just hang tight, you will soon be on a much more powerful server!
