VMware 5.1 Guest Operating System incorrectly chosen

We had a template that was incorrectly specifying Windows 2008 R2 64 bit instead of the correct version (Windows 2012 64 bit).  There have been a few 2012 virtual machines deployed with it and it appears I can change it with the guest operating system pull down menu within the vmware client (edit settings of the vm).  My questions are what is the difference when deploying using 2008 R2 and 2012?  Can I simply change the pull down to correct it?  Should I even worry about it?  So far, regular servers seem fine, however I am now having weird domain controller issues so wasn't sure if it could be related.

The template sets up the hardware to be used in the VMX.

As the hardware for both 2008 and 2012 are the same/similar, it can be changed, but personally I would not worry about it. Before there was a 2012 setting, when we Previewed the 2012 OS in Beta and RC, we would use the 2008 R2 64 bit setting, because it was not available in vSphere.

OS and Templates Settings are there to make deployments easier.....

Just make sure the next servers you build have the correct option/setting.

With changing any setting in a VM in Production, ensure you have a full backup before altering any settings.

Thanks.  Didn't know if there was something under the covers or tweak for 2012 that may make a difference...
