  I used dsync, and had no difficulties.  Here is an excerpt from my notes:

--------------------------------------------
To change mail spool format for user at domain:

Change spool type in dovecot.conf or in database, making note of
original (current) spool type.  Then:

dsync -u "user at domain" mirror "spooltype:/spool/location"
dsync -u "user at domain" mirror "spooltype:/spool/location" (repeat, to
pick up any changes since first run)
--------------------------------------------
