Parallels: don't upgrade virtual machines to Windows 8

updated 11:05 pm EDT, Wed October 24, 2012

Clean installs of the new Microsoft OS should work fine

Virtualization solutions provider Parallels has issued a "critical and urgent Windows 8 service advisory" recommending that users not perform an upgrade to Windows 8 form an existing Windows install. Potential side effects of a botched upgrade include damage to the virtual machine and data loss.

The release is brief, and does not address the specific modes of failure of the upgrade. The Parallels advisory says "We're working hard on completing our testing of the Windows 8 upgrade, and will inform you via in-product notification when you can successfully upgrade to Windows 8." Updates on the status of the Parallels revision can be found on the support pages for the application.

A full installation of Windows 8 without migrating any applications or data "should work just fine" according to the service advisory. Parallels does recommend that users upgrade to the very latest build of Parallels Desktop prior to creating the new virtual machine.

    Doesn't surprise me. Microsoft is not recommending doing an upgrade from Windows 8 pre release either. They want you to do a full install the reinstall all your programs. Some tech sites for Windows is saying you can do an updgrade but you need to follow a set of instructions to accomplish it. MS is nuts. This is going to really endear them with their users. NOT!
