Remaining postupgrade activities
After you complete the activities described in the previous sections, perform the following remaining activities:
- Perform the database backup.
- Perform feature and functionality validation and performance testing.
- Restore the backed-up, upgraded staging server database after the testing is complete.
- Perform any required changes based on issues found in testing.
- Back up the postconfiguration staging server database. You might need a stable point to revert to if you experience issues with delta data migration (DDM).
