You can upgrade from SAS Business Rules Manager 2.1 or 2.2 to SAS Business Rules Manager
3.1.
When you are upgrading
to SAS Business Rules Manager 3.1 on the third maintenance release
of SAS 9.4, you must complete additional installation and configuration
steps. SAS Business Rules Manager 3.1 is integrated with SAS
Lineage. Therefore, two passes of the SAS Deployment Wizard installation
and configuration process are required in order to complete the upgrade.
During the first pass of the SAS Deployment Wizard, it upgrades your
existing deployment. After the upgrade has completed successfully,
the configuration stage begins. After the configuration stage has
completed, you must run the SAS Deployment Wizard again to install
the new product components and to complete the configuration.
The SAS Business Rules Manager
upgrade process supports upgrading to a database from the same vendor
as the database that you are currently using. Upgrading from a database
based on Oracle to a database based on PostgreSQL, or vice versa,
is not supported.
If you are using Oracle
for your SAS Decision Manager database, the upgrade process assumes
that the upgraded environment uses the same instance of Oracle. The
upgrade process does not support moving to a different Oracle database
server.
