Hey @edith_t ,
To update such collection name, one can try using below code in mongosh
var authColl = db.getCollection("Prueba uno");
authColl.renameCollection("prueba");
Alternate way to do the same via query
db[“Prueba uno”].renameCollection(“prueba”)
Note: Please test the code in your test environment and update the code as per your requirements before making any changes to production environment.
