I did a in-place (uninstall VMM2012 Sp1, retain the database, and install VMM2012 R2 point to old database) upgrade. All the steps work fine.
The only problem (so far) is that when I create a new VM using a custom template (for example, Windows 2008 R2), the deploy fail with the following error:
Error (2912)An internal error has occurred trying to contact the vm-scvmm2012.domain.com server: NO_PARAM: NO_PARAM.
WinRM: URL: [http://vm-scvmm2012.domain.com:5985], Verb: [INVOKE], Method: [GetError], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/microsoft/bits/BitsClientJob?JobId={56B8E488-5DB9-4CC1-BEFA-AFF76E1E4D2D}]
Unknown error (0x80072f0d)
Recommended Action
Check that WS-Management service is installed and running on server vm-scvmm2012.domain.com. For more information use the command "winrm helpmsg hresult". If vm-scvmm2012.domain.com is a host/library/update server or a PXE server role then ensure that VMM agent is installed and running. Refer to http://support.microsoft.com/kb/2742275 for more details.

VMM could not offload transfer the file \\vm-scvmm2012.domain.com\MSSCVMMLibrary\VHDs\Template_Windows_2008_R2_SP1.vhdx to C:\ClusterStorage\Volume1\VM-NEWVM\Template_Windows_2008_R2_SP1.vhdx.
Any ideas?
