# Migrate All Connected Apps to External Client Apps (Release Update)

Keep your integrations supported by migrating to external client apps. In Summer '27, Salesforce is ending support for connected apps. Connected apps will keep working, but Salesforce will no longer fix bugs or provide support for the integrations and authorization flows that use them. This update is available starting in Winter ’27 and is enforced for production instances in Summer ’27.

**Where:** This change applies to Lightning Experience in Enterprise, Unlimited, and Developer editions.

**When:** This update is enforced for production instances in Summer ’27.

**How:** From the App Manager in Setup, open the connected app and click **Migrate to External Client App**. The automated process creates an external client app.

To review this update, from Setup, in the Quick Find box, enter Release Updates, and then select **Release Updates**. For Migrate All Connected Apps to External Client Apps, follow the testing and activation steps.
