During an OpsHub migration from local TFS 2013.3 server to VSO, I receive an error message from OpsHub:
com.opshub.exceptions.DataValidationException: OpbsHug-012017: Field mapping with name: Migrate Work Items and Version Control Data Migrate Work Items and Version Control Data | TFS Source 1211589216815 ALM TFS 1211589216816 'All' Test Suite already exists
This only occurs when trying to migrate work items. Code migration works fine on its own. Stack trace from log file shown below:

As per the error message and information provided it looks like you are using TFS 2013 update 3 which is currently not supported by free migration utility. We will update you on same thread once we have support for this tfs version.
Thanks,
