personally, i'd do the mbox->maildir conversion as one of the last steps
after postfix has been tested and shown to be working well for (at
least!) several days, purely so that the whole migration is a steady
sequence of small incremental improvements, each of which can be
performed and tested in turn.
trying to change too much in one go can lead to a real mess.
the key to successful migration is to plan out exactly what you're going
to do, in what order, and test each step as it is completed. if nothing
else, it is very useful to figure out the optimum path (i.e. least
hassle, least downtime, least after-the-fact realising "damn, i should
have done this other step before this one", etc) from where you are now
to where you want to be.

wouldn't it make more sense to:
- install radius on the RH or Mandrake machine
- configure your NAS boxes to use it
- blow away the suse box and install debian
- (optionally) move radius back to it, configure NAS boxes to use it again.
- install apache and start moving vhost clients over
that way you end up with a debian web server rather than suse. much
better.

yep.
also, you might want to eventually move radius to this box too. if
you're not using LDAP or other shared account db, it can be very useful
to have with the radius server on the same machine as the mail server.
/etc/passwd already holds the passwords for login accounts, it's easy to
configure radius to use that.
