So here is the information, but please ask anything that you need to know.

Previous Architecture

DPM SERVER (PHYSICAL SERVER): 

• OS: Server 2008 R2
• DPM 2010 

Hyper-V (PHYSICAL SERVER):

• OS: Server 2008 R2
• VM'S: SERVER 2008 R2

New Architecture

DPM SERVER (PHYSICAL SERVER):

• OS: Server 2008 R2
• DPM 2010

Hyper-V (PHYSICAL SERVER):

• OS: Server 2012 R2
• VM'S: SERVER 2008 R2

PROCESS:

• Shutdown all VM's
• Moved to shared storage
• Loaded existing Hyper-V server with Server 2012 R2
• Moved VM's back
• Started up
• Upgraded Integration tools

Utilizing DPM, configured Protection Group for VM's and connected to host. These backups were running great for a couple years.

Since moving over, the backups of Exchange, etc on the VM's are still working great, but the VM's themselves through the new host fail immediately. I can attempt to Perform a consistency check, but it fails immediately.

The error that I have gotten on each is:

ID:3106 All protection activities for data source will fail until the replica is synchronized with consistency check.

Followed by:

ID:104 An unexpected error occurred while the job was running.

On the Hyper-V host I  only see (which is only showing for the Exchange server):

The Data Exchange integration service is either not enabled, not running or not initialized. However, the service is running. Although it is running.
