Transitioning away from mail_location = maildir:~

[Charles Marcus]

I can't provide specific details as I'm on the road, but I successfully used mmv utility to accomplish something similar - changed mail home from domain/local at domain to just domain/local for about 65 users, took less than a second once I worked out the command (it supports wildcards) . The tricky part was changing the sql backend (was using postfixadmin) after the mmv - I ended up just dumping the sql db, editing the file, then pausing postfix/dovecot, performing the mmv, then restoring the db, and restarted postfix/dovecot, was down for maybe 20 seconds or less...
