Do note that 2.6.6 is anything but new; 2.6.6 is from 2010, and the last legacy release of the 2.6.x series was two years ago. At this point, for new systems, you should be using 2.9.x as the absolute minimum, since 2.8.x is already out as well. See the Postfix announcements page for details; http://www.postfix.org/announcements.html As far as the migration itself; review the documentation for changes, both to settings you have in your configuration as well as changes to default settings, as the gap between 2.0 and whatever you move to is quite big. Start here; http://www.postfix.org/postconf.5.html Once you have reviewed the documentation for anything you might need to change, set it up on the new machine, and test all your assumptions about how it should work. Your '/var/spool/postfix' should be empty, and there should be no need to copy that over. How you migrate stored messages on the server depends on how your users access their mail, which is outside the scope of Postfix. In other words; move to a supported version of Postfix, and test your migration extensively. Good luck! Mvg, Joni
