[Dovecot] sdbox to mdbox

[Joan Moreau]

 Thanks, but this keeps very unclear for me.

 Concretely, I have in my dovecot.conf:

 mail_gid = mail
 mail_location = dbox:/data/mail/%d/%n
 mail_uid = mailusers


 What you are saying is that, I shall :

 1 - plan to have all the new emails in a different folder (say
 "/data/mail2" )
 2 - make a script that go through all users & domains
 3 - for each user (and therefore dbox folder), run "dsync -o
 mail_location=sdbox:/data/mail/%d/%n mirror mdbox:/data/mail2/%d/%n"
 (where %d and %n are updated correctly for each user)
 4 - move /data/mail to /data/mailold and move /data/mail2 /data/mail
 5 - update dovecot.conf with "mail_location = mdbox:/data/mail/%d/%n"
 6 - Only then, restart dovecot in production ?

 ISn't there a way to do that keeping dovecot running ?

 You kind help is very much appreciated

 Joan
