Do one of the following:
If this is a downgrade to a previous Maintenance Release, edit
the installprops.txt file as follows:
ne.load=<previously deployed 11.0.X.X loadname>
Run the upgrade script:
./smUpgrade.pl
OR
If this is a downgrade to a previous patch, run the following
script:
/mcpPatch.pl -smonly
When prompted, select the previous patch to be applied.
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.
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.
