I have written a script that move a mail domain across 2 servers in a multiserver installation. It is very dirty, it copies data from mail_domain and mail_user source db tables to destination db tables, than with rsync copy /var/vmail/domain I don't know if some already did. and if someone is interested in what i did let me know
should be interesting for ispconfig itself. ask till or falko for access to the svn or post the patch here or in the bugtracker: http://bugtracker.ispconfig.org
