Since you don't mention the problems you faced, it's hard to guarantee you 
won't face them again.

I  don't really understand what you mean, but may I assume you are talking 
about local accounts, and not virtual users defined in some sql db?

Do they access emails on POP, IMAP, direct shell access? 

Do you store mail in mbox format or Maildir? Do you intend to change that?

How about just batch recreate all the accounts? You can extract the passwords 
from /etc/shadow into a file in format login:passhash (one per line) and use 
chpasswd to batch reset them, so the process should be fairly transparent to 
the users.

I did this when migrating from slackware to debian.

From fake to fake, I suspect mdadm has a larger userbase, which almost always 
favor bug reporting/fixing. Maybe it has some performance benefit over mdadm, 
but I hardly think it would be noticeable. YMMV.
