Performing V2P migrations

Filed under: vmware — ermac318 @ 2:12 pm

So lots of people perform P2V migrations. In fact, there have been lots of third-party products (such as those from LeoStream and PlateSpin) and first-party products (VMware’s original P2V Assistant and now vCenter Converter), as well as community-supported free products (such as Mike L’s Ultimate P2V).

Back when I did my first server consolidation, we used Ultimate P2V since at the time VMware’s P2V assistant wasn’t free. (BTW VMware, making Converter free was a VERY smart move for ESX adoption!) One of the interesting things I had noticed in the original fix-vmscsi BartPE plugin was the ability to inject not only the VMware SCSI controller drivers into a Windows installation, but also for some standard HP and Dell servers. I actually used these to perform a P2P migration, but never a V2P, though there was no reason I couldn’t have.

Now VMware has (uncharacteristically) actually posted some information in a whitepaper on performing V2P migrations. I say that because VMware’s never talked much about doing V2P migrations; as far as I know this is the first time any official V2P information has been posted by them.

Their strategy revolves around using Sysprep along with the [MassStorageDevices] entry in the sysprep.inf to make the system bootable post-clone. I actually think using the Ultimate P2V system (using fix-vmscsi post-clone) is a more efficient method. I know now that vCenter Converter is free and has a lot of great features that Ultimate P2V has kind of gone out of style, but as you can see from this it still has some great uses!



  1. Thanks for the info! I have messed around with vConverter as well as Visioncores product, and was asked for this info, but it had been awhile since I tested them.
