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.
