I am migrating virtual machines from VMware workstation to our cluster. People were trying to save money and use the workstation product instead of getting another cluster.

I am using VMware vCenter Converter Standalone and one migration died. After correcting a couple things; I tried to rerun but received the following error:

A general system error occurred: Unexpected element tag “ConvertManager” seen while parsing serialized DataObject of type converter.AgentInstanceContent at line7, column 63 while parsing return value of type converter.ServiceInstanceContent, version converter.version.version2 at line 7, columen 0 while parsing SOAP body at line 6, column 0 while parsing SOAP envelope at line 2, column 0 while parsing HTTP response for method retrieveConent on object of type converter.ServiceInstance at line 1, column 0

I checked a few things but no obvious issues. This particular VM was part of a group with a similar configuration and they migrated successfully.

Since it crashed, I checked the programs control panel and found that VMware vCenter Converter Agent was installed.

The agent is installed as part of a conversion and is removed at completion. Since the effort failed, it was left in place. Usually, I can rerun without a problem but every so often the mentioned error happens.

I removed the agent (no reboot needed) and was able to initiate a conversion.
