Text export is the best solution

  1. export configuration
  2. check it for devices's dependend data and get rid of it: especially MACs.
  3. reset target device with no default configuration
  4. import line by line / block by block exported configuration

Search forum for import/export as it is not a trivial task for beginners with no experience what order of CtrlC+CtrlV should be used, however your configuration is quite short and should be easy to copy/paste.

PS. Hardware reset clean the unwanted data. Netinstall too.
