I did the same thing, with no know issues so far.

My old server was running dovecot 1.2.x and i coppied the whole maildir 
structure to the other machine.
Then started Dovecot 2.x and all was fine.

Should be the same as instlling 2.0 over the old 1.2.x version, then it 
uses the old maildir also.

Well test it i would say.
Just do the copy, and try if everything works.
then do it for a final migration.
