Stephen Rose has a nice post over his blog that discusses the history of the the P2V Solution Accelerator and goes into a little more detail about the product. 

“By now the announcements have gone out for the Beta, been blogged about and seen in other social networking channels, so I thought I would do something a bit more in depth on this for the Springboard Blog.
A little (recent) history…

In Fall of 2009 there was a perfect storm of tools and automation to enable something I have wanted to do for some time, automate local physical-to-virtual migration of a Windows client machine and redeliver and integrate that old environment within a new Windows build using full automation. The pieces we had in November 2009 were:

  1. Sysinternals Disk2VHD
  2. Virtual PC with shell integration
  3. RemoteApp hotfixes for Windows XP SP3 and newer clients
  4. Microsoft Deployment Toolkit 2010

At that point, the ingredients were fundamentally there to get everything working. In the Spring another valuable component came online to enable Virtual PC on machines without Hardware Assisted Virtualization. With all of these components in place, it was time to glue everything together and get it working end-to-end. Being a deployment guy, I’ve always been a fan of task sequencing engines and I knew that MDT could do everything I needed to configure the right things at the right times and drop the right components needed in the process.”
