- Do not use the -V option to import data into an empty configuration file. If you use -V against a Rendezvous message with duplicate field names, the error `SXT7075E` occurs.
- Do not use the -Z option to import data into a configuration file that is not empty. Otherwise, all the existing data in the configuration file is lost.
