I just got a new iMac and will be moving everything to it, including Parallels (plus Windows and Quickbooks). I have multiple questions now.... 1) Can I install Parallels, using my existing license/key ? It will be temporary, as in hours or worst case, a day or so. 2) Is it recommended to MOVE my current virtual machine or start over from scratch ? I have no problem starting over. I know it's more time-consuming but sometimes a 'clean slate' is a good start. 2a) I'm thinking I may want to move it because of Windows. I have a license/disc for Windows 8.x (can't remember if it's 8.0 or 8.1) and used the 'free' upgrade to Windows 10. I thought the free upgrade was a time-limited thing so I may not be eligible now. Hmmm, I thought I had more questions.... I'll probably think of them later though !
