I am currently running Windows XP Pro and Parallels build 3214. I want to upgrade my Win OS to Vista Business. Should I do that windows OS upgrade first, within Parallels build 3214 and then upgrade to Parallels 3.0? Or vice versa? I'm trying to figure out best practices here. I don't think anyone has posed this specific question. If it has been asked/answered, please point me to that specific thread. Thanks very much.
