I moved Radio 8 over to my OS X machine this morning following this guide. Everything went smoothly. It had been running on a Win 2000 machine since January, which speaks nicely to their design that I can move the entire system over to a Mac running OS X and not lose any of the content.
Radio 8 has been a good investment. It is used to manage the Jer Zone, winemaking log, EV Conversion pages, even my Resume. It's also used for managing private client-related sites where I post software versions, track features and bugs, and log communications. There is the occassional quirk but overall it is a wonderful tool.
