Upgrade
When you open a Quadri model that is older than the client version you are using, you will be asked whether you will upgrade the model or not.
If you answer yes to this, an upgrade process that may include one or all of these steps will start:
Upgrade the model to refer to the latest version of the Feature Catalogue.
Upgrade features that have a changed feature type definition.
If you answer no, the model will not be opened.
