I was hoping to have avoided going through all the trouble of setting up the old ESXi environment and doing vMotion, by using the stand alone converter. It's only 8-10 VMs that I'm dealing with.
None of the VMs are GPT partitioned. They are all Windows 2008 R2 server and Windows 7 hosts. I'm suspect as to why this isn't working, since I was able to do the 'exact' same type of migration at another location between an older ESXi server, and a new ESXi 5.5U2 server, without incident.
