Hi Friends, I would like to ask you a suggestion: I need to migrate a imap server to a new one and then dismiss the old one. Reading from relative Dovecot documentation page (https://wiki.dovecot.org/Migration), more tools are shown: UW-IMAP's mailutil, imapsync, YippieMove and Larch. The each mail servers are Linux based, one of this (mine) is Dovecot. Based on your experience which of these tools would be preferable to use? Thank you very much Davide
Hi, I vouch for imapsync. Have used it in the past with quite a big amount of emails. cheers. x0p> Hi Friends, > I would like to ask you a suggestion: > I need to migrate a imap server to a new one and then dismiss the old > one. > Reading from relative Dovecot documentation page > (https://wiki.dovecot.org/Migration), more tools are shown: > > UW-IMAP's mailutil, imapsync, YippieMove and Larch. > > The each mail servers are Linux based, one of this (mine) is Dovecot. > Based on your experience which of these tools would be preferable to > use? > > > Thank you very much > > Davide >
Imapsync for sure. Have used it for both IMAP to IMAP and IMAP to Exchange migrations. Works great.> On Dec 3, 2017, at 2:08 PM, x9p <dovecot at x9p.org> wrote: > > Hi, > > I vouch for imapsync.

With every other tool you will face end users needing to invalidate their local caches and redownloading all headers if not also all mail bodies. Sami

Been using imapsync for large scale migrations from external servers to our dovecot setup. Users don't even see it when the key is switched (DNS changes). Go for it.
