I was still running Snow Leopard 10.6.8 and recently upgraded to Yosemite after backing up. I had Parallels 5.0 and was running Windows 7 on it but now it doesn't work. My question is, if I upgrade to Parallels 10 now while running Yosemite, will I get all my data that was on that partitioned drive? I had some scrapbooking software on it that only runs on Windows (hence, why I used Parallels). Or am I going to have to restore my back up (10.6.8), upgrade Parallels and then reinstall Yosemite? And will my Windows 7 run on Parallels 10? I have a MacBook Pro 5,3 (mid 2009) 2.8 ghz Intel Core 2 duo, 4 gb memory. Thanks!
