Hi!
There is no "transport request" in SAP ME, however, there is Configuration Data Transfer Export/Import activity which can export the data to ZIP file at the source site and then import that file at the destination site.
CDT activity can utilize CTS+ as a transport channel but I would suggest ZIP file instead because the file can be edited manually in case of any issue or if you want to remove some data.
For details, please consult this How-To Guide.
Regards,
