Copy the shadow, passwd and group files from the old machine to the new
one. Generally, you can just copy the information from the old file to the
new file, but you have to watch for duplicating the uid/gid numbers.

Be sure to make backups of both sets of files before copying anything, and
be sure to have a working and tested boot disk handy so you can boot into
single mode to fix any fubars should they occur.

safe to copy the httpd.conf file over

/etc/php.ini. If you're upgrading versions, do a diff between the ini
files. A lot of people don't edit this file, so the point is moot if you
don't either.

Make sure you uninstall ipchains and unload the ipchains module on the new
machine. Buggers made it default in 7.3 again.

Postfix is a breeze to set up in comparison.
