There are important pieces of the procedure in the Systems and Network
Admin docs, but it isn't exactly straightforward.

1. On the NEW server, collect all the necessary files and run "ypinit -m".

2. On the OLD server, run ypxfr and get all of the files from the NEW
   server (or ftp /var/yp/{domain}/* if you think it's faster).

3. Go back to the NEW server and touch all the files and run make from
   /var/yp, or just yppush everything.

The key to all of this is that the master server's name gets put in all of
the maps. You need to build the maps with the new name, and then get them
out to all of the slave servers. If you have more than one slave, then you
can use yppush to help you, once you've gotten the new files to the old
server. If you do the "ypinit" procedure "by hand", remember to recreate
the ypservers map with the new server as the first entry.
