I've converted around 4-500.000 users from maildir to mdbox by the
following on a server configured for using MDBOX as default:

  1 - Search for all users with mailMessageStore attribute in LDAP
  2 - Convert user to mdbox:
	dsync -v -u "$username" mirror maildir:"$maildir" + check returncode
	dsync -v -u "$username" mirror maildir:"$maildir" + check returncode
  3 - Delete mailMessageStore attribute from LDAP and add "mailLocation: mdbox:~/mdbox"
  4 - pkill -HUP -u dovecot -f dovecot/auth -- to make sure auth cache is updated
  5 - doveadm kick "$username" -- on all servers, in case user was logged in..
  6 - Do final sync: dsync -v -u "$username" mirror maildir:"$maildir"
  7 - Delete maildir.

Only 26554 users left to convert..
