Upgrade your data action extensions to improve the data action code or upgrade the metadata to enable existing data actions to work with new data action code.

1. Increase the version number of your data action.

   For example, if your data action is called company.MyDataAction, then search mydataaction.js for the mydataaction.MyDataAction.VERSION property. If it's currently set to 1.0.0 then change it to 1.0.1.

2. Add a static upgrade(oOldDataActionJS) method to your data action's class.

   If the VERSION property differs from the sVersion value stored in the data action metadata then the Data Action Manager calls the static upgrade() method on your data action's class.

3. Implement your upgrade() method by calling the upgrade() method on the superclass and capture its response.
4. Continue to implement your upgrade() method by making further edits to the partially upgraded data action JSON returned by the superclass, until the object matches the correct set of properties required by your latest Knockout Model.
5. To finish call var oUpgradedDataAction = dataaction.AbstractDataAction.createFromJS(fDataActionClass, sFullyQualifiedDataActionClassName, oUpgradedDataActionJS).

   This command constructs a new instance of your data action from the upgraded data action JSON and returns oUpgradedDataAction.getSettings().
