Or upgrade to 2.0.5 on the new server and still use doveadm - this is
probably best if you can...

Honestly though, I'm not really the best one to be advising you on this
(I know enough to be dangerous, have played with the tools, but don't
provide any warranties, etc)...

You can convert one or a few at a time, and I don't see any reason why
you couldn't 'nice' the process somehow (not sure exactly how though)...

I think the best thing would be to do what you need to do to get 2.0.5
installed on the new server, make sure it is working properly in your
environment and for your use case, then migrate the users.

How many users do you have? I'm fairly certain there is a good way to do
this mostly automated in batches...
