Why would you want to have the cleartext passwords for all users to be
able to migrate? What you could do is start 'vipw' as root on the
original server, save that file to disk under a different name, start
'vipw' on the new server, and read in the saved file, and save it again.

Next you'd have to make sure the groups are in tact. Either copy it
(/etc/group), or manually set it to the correct values.

That should do the trick. 
That is, IF your new server is a fresh FBSD install.
