  • Similar to method 2, this method allows us to check that the class that we are migrating is the right class.
  • We have complete control of what to do with the old properties. Typically they will be removed so that there is no name collision with new properties added. Thus we avoid duplicated properties.
  • By saving the older values, we can manipulate the information in the restoring step as we want, and assign the corresponding values to the new properties.
