After downloading and installing the new Standalone Converter, I ran into several issues across many different physical machines, all of which reported back the following error message “agent.internal.fault.PlatformError.summary”, and “Failed to clone volume”.

Some of the conversions would fail immediately, some in the 10-15% completion range, and a few that had gone as far as 38%. I could find nothing in common on the physical servers.

Long story short, the simple and 100% effective fix was to hard code the speed and duplex on the active NIC(s) on the source server. Doing this immediately fixed the problem, and cut the time to convert the machines by approximately a third.

Simple fixes are a beautiful thing.
