dovecot - May 2017 - Backing up and restoring maildir folders

Hello,

I am migrating to a different distribution of  Linux that involves
changing to an earlier version of dovecot (2.2.22 to 2.2.13).  As part of
this process, I will be copying several maildirs to the new machine.  One
of these has a number of files and directories that resemble this one
example:

cur/
dovecot.index
dovecot.index.cache
dovecot.index.log
dovecot.mailbox.log
dovecot-uidlist
dovecot-uidvalidity
dovecot-uidvalidity.59206030
.Drafts/
new/
.Sent/
subscriptions
tmp/
.Trash/

Is it good enough to simply stop dovecot and tar this folder, and others
like it, and copy them back to a similar location on the new installation?
 I haven't yet seen anything that resembles an official or standardized
backup/recovery method for dovecot.

With thanks and appreciation,

Tim Legg

Backing up maildir is easy, just backup (and restore) the whole 
thing and, usually, that's as simple as that.

     However, for saving some backup space if that's a matter, i would 
exclude only the 'dovecot.index.cache*' files, as these can be rebuilt 
(some performance hit after the restore, of course) but, in some 
servers, that makes almost a 10% difference to me.

     Besides the cache files, you really should backup everything inside 
the maildir folders.
