Yesterday I'vemigrated Dovecot mail archive between two servers using the procedure below:
- Createon the new server the same email accounts existing on the old server.
- Transferthe "tarred" mail folder from the old to the new server. For testingpurposes, on Outlook 2007 I've deleted a .pst cache file, forcing the client todownload all emails again.
The switchwas absolutely transparent without any problem. All the emails were availableand Outlook 2007 noticed no changes. Can Iconsider this a correct procedure or should I use some tools like Dsync ?
If you do not change the mail storage format (Maildir -> dbox, or something like that), do not change 32bit -> 64bit, big / little endian a.s.o.
and if you make sure the old mailbox is not accessed, while you copy the data over,
it should work :-)
In fact, I use "rsync".
Imapsync is easier. Made migration from dovecot to Office 365, then back to dovecot painless and easy, and can be done while both systems are live.
