Resolution
Validate that each troubleshooting step below is true for your environment. The steps will provide instructions or a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Do not skip a step.
If you have teamed NICs on your vCenter Server, ESX/ESXi hosts, and your source system, ensure that the NIC team is working properly. VMware Converter may be unable to determine the target and/or source server if the NIC team has failed over or is not communicating. For help troubleshooting this issue, see NIC team failover, failback, or vMotion results in loss of network connectivity (1003969).
