I did what Aki said. Actually I moved it all to a new server and to docker containers. From Dovecot 2.2 to 2.3. And it worked fine. Of course one always forget something - the path for the certificates, the different directory for mounting storage, etc.
But am surprise and happy that it worked very well. __ Francis Augusto Medeiros-Logeay Oslo, Norway Sent from a mobile device / Enviado a partir de dispositivo móvel > On 29 May 2020, at 19:33, Aki Tuomi <aki.tu...@open-xchange.com> wrote: > > >> On 29/05/2020 20:12 Ralph Seichter <ab...@monksofcool.net> wrote: >> >> >> * David Mehler: >> >>> I'd ideally like to back up all the mails in the maildir location, >>> copy that over, load in my configuration files, and bring the system >>> back up. >> >> I don't think this qualifies as "ideal" for migration.
