I tried that a week or so ago, with a 'dsync -R backup', but got the funny named directories, so I read more and am trying the 'dsync mirror' which doesn't require the -R.
How long does the sync step take for you? (Normalize to # of messages..)

I've found that when going in one direction, using "backup -R" rather than mirror, works better. I'm going from mbox to sdbox, but doing roughly the same thing you are, rsync and then dsync.

I am moving mail in a series of steps:
cd ( to mail user home directory ) mkdir Maildir
# rsync mail from source system (hoho4) to current (hoho0) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/
This step takes about 37 minutes the first time
- # dsync mirror/convert to sdbox format on current system time dsync mirror maildir:~/Maildir
This step takes about 858 minutes (!!)
Looking at -D messages indicates that dsync is deciding between duplicates much of the time.
Looking at the results in a mail browser (Evolution), it seems fine, although the latest mails are not there.
- # pick up more current mail - use same script as in 1) time rsync -arv --times hoho4:/home/bobgus/Maildir/ /home/bobgus/Maildir/
This step takes about 5 minutes although this varies depending on the amount of new mail.
- # repeat the 2) dsync step time dsync mirror maildir:~/Maildir
This is where things look peculiar. When I look at the directory of sdbox/mailboxes, I see duplicated directories

The 2nd dsync step has not completed yet. I'm wondering whether the extra directory will be magically moved into the older directory.
(This is unlikely because the file names are duplicated in the new directory)
Is this expected behavior? Are there command changes I can make to speed up the process? Eliminate the duplicate directories?
