I would not use dsync here:
use rsync, one mail location after another with the paritcular source and 
target location.

Maildir is relative to the mail location, so no problem. You copy all mail 
related data, too; e.g. ACLs, keywords, subscription. You might run into 
problems with the cache and index files, because you downgrade. But I do 
not think, the format changed between 2.2.10 & 2.2.9.

Here, too. Do it via filesystem level commands.
