Have you actually done it?

I have Dovecot set up on port 10993, but before I actually fire it up, I 
want to make sure it isn't going to hose anything. I will backup the 
maildirs in question before I do bring dovecot up, of course, but still 
wouldn't want to do anything that might mess anything up.

The index files are my main concern.

I guess the safest thing to do is to tell postfix to queue his mail so 
nothing gets delivered while he's messing around, then let him play - 
see how fast folders load, etc (he's got some pretty big ones, 30,000 
messages or more)...

Thanks - I'll wait and see if anyone else chimes in - I like to get more 
than one opinion, and to hear from at least one person who has actually 
done what I'm about to do, when trying something like this (that I've 
never done before)...

Charles
