Looking for some advice on best practice here.
I currently have a single server running both Exchange 2003 and BESX 5 and it is working fine with about 150 mailboxes with 40 on the BESX.
We have recently installed a new server that is going to be running Exchange 2010 and BESX so we can decomission the original.
My question is the best way to transfer over these two complicated systems; Shall I move the mailboxes over first and then the BESX accounts or shall I move the BESX accounts over first and then move the mailboxes?
(Assuming that it is possible for two BESX installs to transfer accounts)
Looking for the least bumpy road here as it is a live system. Doesn't have to be done in a rush so it can function for a week or so with only one move done.
Any advice would be appreciated.
