Yes it is possible. As long as all the clients can understand md5
encrypted passwords you can mix crypt and md5 encrypted passwords
in the same password file/map.

Configure the clients to use md5 passwords using authconfig. The next
users changes their password the passwd command will md5 encrypt it.
Once all the users have changed their passwords you'll have all md5
passwords. If you configure the server to generate md5 passwords,
yppasswd will work the same.
