Release to Production Environment in Dynamics 365 F&O

 After you've successfully applied the update in the sandbox environment and are ready to move the update over to the production environment, follow these steps to mark an update as a release candidate.

1. Open the environment history page by selecting History > Environment changes on the environment details page.

2. Select the update to move over to the production environment.

3. In the details for the update, select Mark as release candidate.

The Is Release Candidate option is set to Yes.

After you've marked an update as a release candidate, follow these steps to update your environment.

1. Open the environment details page for the production environment.

2. Select Maintain > Update environment to apply an update.

3. In the Available sandboxes list, select the source sandbox environment where the update was applied, validated, and marked as a release candidate.

4. In the grid, select the update to apply to the production environment. This grid shows only updates that have been marked as release candidates.

5. In the Downtime start field, select a date and time. The environment will be taken down for servicing at the specified time on the specified date. The Downtime end is calculated automatically based on the expected duration.

No lead time is required for this update.

6. Select Schedule. LCS runs validations to make sure that the selected update is applicable to the environment. To prevent downgrade of the environment, the update isn't allowed if its application version is lower than the current environment version. Additionally, customers are asked to confirm that they want the update to proceed.

If the update is successfully scheduled, an email notification is sent to all project stakeholders.

The status in the upper-right corner of the environment details page changes from Queued to Servicing. Then, when the update is completed, the status changes to Deployed.

All stakeholders are notified of the progress of the operation.

7. After the update is completed, the environment history is updated. To view the environment history, select History > Environment changes on the environment details page.

8. You can also download the logs from the environment history page.

9. After the validations are completed, you can sign-off on the update from the environment history page by selecting either Sign off or Sign off with issues.
