Use this procedure to prepare rollback requirements before upgrading Cisco Optical Network Controller. It helps you complete the related Cisco Optical Network Controller workflow and verify the expected result.
Rollback preparation helps you restore Cisco Optical Network Controller to a previous version when a valid database backup is available.
Before you begin
Follow this step to prepare for rollback scenarios.
Procedure
-
Back up the database before upgrades.
-
Install the older release using the matching OVA file when rollback is required.
-
Restore the database backup after the installation completes.
Direct downgrades to older releases are not supported by Cisco Optical Network Controller. You can revert to a previous version only if a backup of the target Cisco Optical Network Controller database was created before the upgrade. For more details, see Backup and Restore Database.
For detailed instructions, see Backup and Restore Database.
The rollback prerequisites are identified before the Cisco Optical Network Controller upgrade.
