MT uses plesk for their VPS, but currently I am using gs (grid server) which has its own custom panel. Even if they had plesk or something similar for migration, it wouldn't help because I want to move to slicehost/linode and they are non-managed server, so they don't use plesk/cpanel (to the best of my knowledge). Almost all migration needs to be manual, its not difficult, its just pain in the butt repetitive manual work and has potential for lot of things going south.
