Consider the following guidelines before you import the extension assets:
•Set up the prerequisite MDM SaaS business application.
•Import the extension assets before you customize the business entities. You can safely import multiple extension assets that use different business entities and in different MDM SaaS business applications. When you import the assets in an environment that already has an extension with the same business entities, the import fails.
•After you import the assets, consider them as your custom assets.
•Once you deploy an extension, upgrading to a newer version of the extension isn't supported.
