I have the same problem.
Ordinary climatological station, (KAVADARCI, 0-20000-0-13599, no data exchange) closed in 1996. In 2015 near the old location (2-3 km, same city) we activated AWS which is now going into international exchange. To register this new station in OSCAR I want to use the name of the original station (normally with new coordinates and new WIGOS ID 0-807-0-KAVADARCI) but OSCAR does not allow the same name (although ID and coordinates are different). Since the data from the first / old station was not in international exchange, I have the idea to delete the closed old station from OSCAR first, and register it again in OSCAR under the new name (without changing original ID and coordinates) and take its name for the new AWS. Could this (coordinate and WIGOS ID of the old station will remain the same) cause some problem in some system???
Please for advices
