Not sure how to give your single Domino server a (cluster) mate without affecting your users? Ever wanted to find out what exactly is involved in migrating a live Domino server from Windows to Linux? Come watch Charles Robinson and Franziska Whitlock not only explain the whole process but also DEMO it live in 60 minutes.
Should I ask Paul to let us work on the production servers? ;-)
P.S. This is why I dropped the hint that I do admin as well as development.
