Currently, all our Internet services (email, web, mailing lists, shell accounts) run on 2 AIX systems.

We want to move a portion of our current Internet functionality to more modern systems, to allow more people to share in the work, as there are more people familiar with Linux than AIX. We'll also be able to do things that we hadn't be able to before, due to older software. SpamAssassin and PHP are 2 of the major things we want to start using.

One of my (Craig's) personal goals is to move management of web content to a through-the-web content management interface.

The current systems will remain in some capacities. (At the very least, they will have shell access to play around with AIX.)

Functionality will be migrated piece-by-piece, and no piece will be moved until it is ready.
