[X4U] convert POP to IMAP

[riteme]

hello - I've been following the "can apple's mail  pick up gmail  
thread" which actually convinced me to change my dot mac account from  
POP to IMAP. reason being I have an iphone and want it all to be in  
sync with messages read.

My concern is of course not to mess things up .... my question is what  
to do with all the folders i use - 7 years of email all filed into  
nested hierarchal folders.
-I'm under the impression i can simply drag these folders into the new  
imap account and they will migrate.
- or do i create new folders and then drag the messages?

this also might be a good time however to archive folders i no longer  
use, ie old jobs, and prune this all down - on the other hand, if i  
migrate them they are backed up again.

another question is rules. i assume they will simply work .....

I've been reading various "how to" migrate and it seems fairly  
straightforward - is there anything in particular anyone's learned  
doing this that i should be aware of?

as an aside, this might help someone else - as an interim step  i set  
up another gmail account and configured it to fetch my dot mac mail -  
then set THAT account up on my iphone.   this is pretty neat.   i  
mention it because if you have a POP account, it's a great way to  
seamlessly back up your email (skip the iphone step)  as it goes to  
both accounts, dot mac and the gmail. (did i explain that clearly).

thanks for the help, eric
