If you have separate sandbox and production orgs, we recommend the following steps to be followed to ensure that your extended context definitions are successful.
- Upgrade your sandbox org to Summer ’26.
- Ensure that you manually sync your custom extended context definitions. Click Sync Now on the Custom Definitions tab of the Context Definition page to complete the sync process.

- Upgrade your production orgs to Summer ’26.
- Package and deploy your extended context definitions from your sandbox org to your production org.
