Running bootcamp/PD6 Windows XP. Want to upgrade to PD7 and buy Win7. Looked at this a few months back, but apple would not allow an upgrade path from win XP to win 7 you had to purchase a full version. Can I: 1. Use my existing XP bootcamp install to upgrade to win 7 via parallel 7? 2. Use pd7 to upgrade my bootcamp installation as well? 3. Create a new vm with a fresh version of win 7 and keep my existing XP bootcamp? 4. Use the windows version purchased through parallels store to create a new fresh bootcamp? I realize that some of these scenarios overlap, some are mutually exclusive. Finally what are the windows prices in the parallels store? Possible to see the store prior to purchase pd7?
