Arrggh I started on my mission to move Plesk from a win 2003 web edition server to a 2008r2 web server at 22:00 last night. Now 4 hours later I'm literally further behind than when I started. The Plesk migration manager SUCKS. I have 1TB of content/mailboxes/databases (mainly mailboxes though) and it won't let me only choose some of the stuff to migrate. At the rate it was going it would take about 7 days of downtime to migrate lol.
Anyway try to play with it a bit to speed things up but killed the entire new install of Plesk. Of course it has no reinstall option so I have had to reinstall the entire 2008 r2 installation and installing Plesk again just to have another go. I need to be finished before 0830 so don't think I'm getting a minute of sleep tonight!
God damn Plesk, its such a crappy program, costs about $60NZD a month and you have to pay for every bit of support, even if its a bug within the program. I don't know why I persist....
