We want to make an update to our E4 based RCP and want to modify e.g. the Menu-Structure of our application but don't want to clear the persisted state.

The user must be able to keep his settings to Perspectives and the new perspectives that he has added dynamicly to the application model at runtime.

Is there a way to only update parts of the persisted Data in the application model?

You could write a model processor (runs on every startup) that checks the model for a tag that you provide, and if not present then performs some changes.
