dovecot - Aug 2009 - Migrating Emails from 1.0.15 to 1.2.2

I need to copy some email storage from a Dovecot Server running 1.0.15  
into another Dovecot Server running 1.2.2.
I know that I can use imapsync (perhaps this is the proper way)

But I was just wondering, if I can just run Rsync to do that transfer: 
Will I run against some incompatibility formats between these two versions?

M.A.

There are some small differences, but I think it's safe to just use
rsync. You might get some "corrupted index file" or something errors
for
a while, but they should get fixed automatically.
