Encrypted Password Portability Between releases

Hey everyone... cryptography is not really my strong point and I'm
trying to do something I thought should have been fairly easy. We have
a number of machines running various versions of FreeBSD from
4.7-RELEASE to 4.8-STABLE. Our password files for our users are
generated through passwords which are currently being stored in plain
text. I wish to encrypt these on a central server and store them in the
database for better security, however I'm running into some problems.
It appears to work on some systems and some systems it does not. I have
tried DES and MD5 encryption.
Most of these systems have been upgraded from much earlier releases of
the 4 branch, and the passwords of users not generated from the database
seem to have been find after each upgrade. So my question is, what am I
doing wrong? Is there a way to encrypt a password on one system and
have it work on all FreeBSD machines no matter what release its running?
If I encrypt on a 4.7 box will it work on a 4.8 system, just not the
other way around?
Thanks for any help of information you can provide.
