How do I figure out how the processor is configured or would it be 64-bit because the Host is?

I have a 32-bit computer (OS) that is running on a Windows Server 2012 R2 Hyper-v host. I would like to upgrade to 64-bit. I figure this was a p2v move by my predecessor. Can I do an in place upgrade? How do I figure out how the processor is configured or would it be 64-bit because the Host is?

Regards,
DJ

If you are running a 32-bit VM, because the VM settings are set to 32-bit, and OS code is 32-bit, you will find most of the time in-place upgrades are NOT SUPPORTED. (from 32-bit to 64 bit).

Time to install a new VM and OS, and transfer the services.

(even if the Host CPU is a 64 bit CPU).

To run a 64-bit OS, the VM settings need to be set to 64-bit.

Check and run the upgrade and see what error messages occur.

Thank you. I knew that was the answer but wanted to hear it from someone with more knowledge on the subject then me. As I have supported VM for sometime, I'm still fairly new to the admin side of it.

 One follow up question, what exactly do you mean by, To run a 64-bit OS, the VM settings need to be set to 64-bit. I don't recall seeing this when I created a VM. However, I've never created a 32-bit VM.

Check how the VM has been configured. Edit the VM settings on the Host to check!

e.g. the selected OS!
