ImportExportCSV consists of two modules that will export resources and their current TV values to a CSV file so they can be imported to another site. Template and TV information is stored by name, not ID, and provided the receiving end has templates and TVs with the same names, these will be preserved.
Details of operation and a list of fields that are processed on import are in the package's Readme file.
