[Dovecot] Maturity of dbox

Hi,

I am contemplating migrating from maildir to dbox. However, I wonder about the maturity of the dbox code, as it appears to not be widely used. Does anybody have some success stories?

My primary driver is to have non-changing file names, and thus smaller backup deltas. Are there other advantages that I should pursue?

I read in the wiki that the migration is straightforward, but I did not manage to find an exact description. Pointers? Also, is it possible to migrate back, should it not work out?

Thanks, Anders.
