The recommended method to upgrade Custom Properties is to install the latest Custom Properties installer file, that will automatically perform the following actions:

  1. update the database tables, if required
  2. update components, modules and plugins
  3. install JoomFish content element
  4. install third party content element connectors

Please note that your data will not be altered by the operation: either your custom properties and their assignments will remain.

We strongly recommend to perform a DB backup anyway, before attempting an upgrade. Better safe than sorry.
