I've been using RU (free key) for a number of months now, and think I am ready to upgrade to a paid per operator license. I'd like to know the exact steps I need to take to migrate from the free license key to the paid key. Do I have to uninstall/reinstall any software, either on the remote hosts or my viewer computers? Is the migration as easy as installing the paid key and removing the free key from the key bank? Can I do all this remotely (a few of the remote hosts are physically a few hundred miles away)?
