SX, unfortunately
Is this possible? I can't find anything concrete either way. Server running hyper-v server 2012 R2 that has 2 VMs running Server 2012 R2.

Seems I can't install the drivers for my video card to run Remote FX on a core installation so I need to change to a normal 2012 R2 install on the host. Can I upgrade in place without the hassle of taking the VMs off?

I don't mean I have a core install of Server 2012 R2 - I know I can upgrade to the GUI version, it's the Hyper-V server that is installed.
 
It is possible to upgrade from Hyper V server to 2012. Always take a backup first though.

Steps 1 and 2 is only for mission critical servers. You may need to check if Hyper V is not installed default directories though, otherwise it may overwrite the configuration. If it's all default, backup your configuration and VM files to another location on the hard disk.

*EDIT*

Just to clarify http://www.aidanfinn.com/?p=14943

Would recommend backing up the Hyper V config files regardless, it appears to only apply to clustered Hyper-V servers or Master/Slave configs where that needs to be done.

Fantastic thanks - I'd found that 2nd link but that is referring to Hyper -v 2012 to Hyper-v 2012 R2. But that first link looks the business.

I do have the VMs replicated just in case but I don't have sufficient licences to ACTUALLY fail over (this is my home setup). The whole box is bare metalled to an RDX cart so if I do bugger it up I should be ok.

I do this at home to learn more without knackering the critical stuff at work, but boy do I dig myself some holes :p

The hard way it is then.
 
Might help you.

To convert from Server Core mode to Server with a GUI mode when the server was initially installed in Server Core mode

Determine the index number for a Server with a GUI image (for example, SERVERDATACENTER, not SERVERDATACENTERCORE) using this cmdlet: Get-WindowsImage -ImagePath <path to wim>\install.wim
Run Install-WindowsFeature Server-Gui-Mgmt-Infra, Server-Gui-Shell –Restart –Source wim:<path to wim>\install.wim:<Index # from step 1>
Alternatively, if you want to use Windows Update as the source instead of a WIM file, use this Windows PowerShell cmdlet:
Install-WindowsFeature Server-Gui-Mgmt-Infra,Server-Gui-Shell –Restart
