Downgrading a database
Use this procedure to downgrade the database in the event the upgrade of a replicated database fails or if performing a complete system downgrade.
WARNING
When an AS 5300 database server is downgraded, the existing database is overwritten with a backup copy during database restoration. As a result, all provisioning and configuration changes made to the database since the backup copy was created are lost.
A downgrade of the database server should only be performed if all other system recovery options have failed.
Prerequisites
•The database can only be downgraded to a version which had been successfully deployed in the past.
•The version of the load that is being downgraded to exists on the Element Management server.
Attention: Any attempt to downgrade the database to a version other than those listed above will fail because there is no associated backup from which to restore the database.
