I always just copy over the files when no other process is using them.
/etc/master.passwd /etc/passwd /etc/group

I then run

/usr/sbin/pwd_mkdb -p /etc/master.passwd

on the new machine to generate the passwd databases.

Try to look for a flag one can use with rsync to keep modification time,
           access time, file flags, file mode, user ID, and group ID as
           allowed by permissions...
