Weird storage vMotion issue

I had a server template that I created on a ESXi 4.1 cluster and moved to a ESXi 5 cluster. After I did that, I upgraded the hardware version and remade it into a template and left it at that. I had been successfully deploying VM's from this template for a few months so I never thought there was something wrong. Well today I've been moving VM's to a new storage cluster on my vSphere 5 data-center using storage vMotion and when I got to this particular server, I converted it back into virtual machine and tried to vMotion it to the cluster. Well at 99% it fails with an "invalid configuration for device 12" error.

Huh?

Some searching turned up a buried post saying that it was an issue with the MAC address on the vnic. So I removed the old nic and added a new one and presto! Storage vMotion worked.

Weird.
