My company would like to get off of Unix (HP-UX) because it's costing us too much money. Is it better to do it one app at a time? Should we start with file-and-print or NIS or DNS?
If you're using an HP-UX server to run your DNS, that might be a good place to start. DNS is pretty much DNS on any server. The config files just need to be properly cut-over and/or modified, and everything should be tested locally before notifying anyone of your change. HP, like IBM, is a big proponent of Linux today. Start with this HP link and do as much research and preparation as you can. Make sure you train your staff appropriately.
