Workspaces that were created with older versions of Storyboard Designer can be used directly with newer versions of Storyboard Designer but may require additional import steps to be followed to update to interim versions. Storyboard 4 will import project content from Storyboard 1.x, 2.x and 3.x projects.

Once a model file(*.gde) has been saved with a newer version of Storyboard Designer, the model file will be automatically converted to that version of Storyboard Designer, making it incompatible with older versions of Storyboard Designer. Users migrating to new versions of Storyboard Suite should take care to save and archive a snapshot of their project if they plan on upading it with an older Storyboard Desginer environment.

If a new model file is required to be used in an older Storyboard Designer environment, the best approach to 'back migrate' is to export the application to a Storyboard Engine deployent from the newer version of Designer and then in the older version of Designer, use the import Storyboard Embedded Engine option to create a new Designer project. This export/import will cause certain items to be lost, such as notes and unused layers, and incompatible features will not be able to be transferred to the old model.

Storyboard Engine deployment files are also versioned with each release as the file structure changes, but Storyboard Designer maintains import support support for all versions of the engine.
