Details on how to upgrade are available at:
http://dev.mysql.com/doc/mysql/en/upgrade.html
It seems that the 4.0.x branche will not live very long anymore, so
upgrading to 4.1.x (via 4.0) might be a good idea if he wants to upgrade.
http://dev.mysql.com/doc/mysql/en/news.html
Lists all the changes in each version. The major features can be found
in the D.2 and D.3 documents (for 4.1 and 4.0).
As a hoster he will probably also need to support PHP, etc. There is
also a nice book by Adam Trachtenberg: "Upgrading to PHP5" (O'Reilly,
July, 2004, 352 p., ISBN 0596006365) which also contains information on
how to migrate to PHP5/MySQL4.1 in several steps.
