Well, if you know the RIGHT way - just share it with the rest of us.
I was asking Timo before and as far as I understood - there is no way of 
converting mbox to Maildir without losing message UIDs.
And given that we already have huge mailboxes, that means that every 
user, connecting to the server after the conversion will need to
redownload all the messages and delete all the messages in the local 
cache. Just imagine that user with ~5Gb of mail across 5-10 folders
connect from home not-so-fast DSL line to check email and has to wait 
until the client rechecks all the mail.... No, this is not right.
Exactly as Don Russell wrote - "no data loss, but it isn't pretty". And 
this is the only reason I don't migrate to Maildir. I really want to do it,
but this is not something I can do to my users.
