Hi Iro
We do not support TDS to MGCP, however, we do support the more common workflow of MGCP to TDS.
You can find a variety of cross-reference database files in the TDS Data Conversion folder:
<install>ArcGIS\EsriDefenseMapping\Desktop10.x\Tds\DataConversion
Data can be loaded using the Preload Validate and Data Loader tools on the Production Mapping toolbar in ArcCatalog.
Regards,
Bo
