Question :

I have a VM that is set to Windows Server 2012 (x64) but I have upgraded this VM to W2K16 (1607). I would like to change the setting for the configured OS to reflect W2K16 under the settings for the VM, VM Options, General Options. What are the implications of doing so? This VM is a backup DC so i do not want anything negative to happen to the OS and operatiion of this VM. Please advise. Thank you!

With changing the guest OS in the VM's settings, you shouldn't experience any issues.

As mentioned in the documentation:

Changing the guest operating system type after the virtual machine is created does not retroactively change those settings. It affects the recommendations and setting ranges offered after the change.

Must have missed that line. Looks like it is safe to do then. TY
