The other day I was trying VMware Workstation 10. I can't remember if previous release was able to downgrade the virtual hardware, but the release 10 of Workstation can. I was actually trying to upload a Windows 2012 R2 server VM which I installed by using Workstation. This is something that has been around since version 8. I found out that I can downgrade virtual hardware with the latest release.
My lab is currently running the latest release of vSphere 5.1. So when I wanted to use Workstation to upload that VM to my cluster, Workstation was complaining that the destination cannot run my vmx-10 virtual hardware. True. And the message said that I have to downgrade the VM.
That surprised me as I was practically certain that once your virtual machine hardware being upgraded there is no way to go back…. Here is the way to do it.
Right click the VM > Manage Hardware compatibility > A wizard will pops up showing you to which version of virtual hardware you want to downgrade.
Once you click next, you'll see a radio button choice selected on “Create a new clone of this virtual machine” . The other choice is Alter This virtual machine. It's up to you….. I would say if the VM is important take the first option!
I took the second option as I have been testing the uploads/downloads etc, so I did not really care if the VM gets corrupted. But I've tried twice and it worked like a charm. So what have we learned? VMware Workstation 10 is the best complementary tool for an enterprise admin.
