Upgrading an FMW 11.1.1.7 Instance to–and Downgrading it from–FMW 11.1.1.9

You can use the CLI to migrate your JCS-SaaS Extension instances provision with the 16.4.5 (or earlier) release from FMW 11.1.1.7 binaries to FMW 11.1.1.9 and, if necessary, revert those specific instances back from FMW 11.1.1.7 to FMW 11.1.1.9.

JCS-SaaS Extension supports the FMW 11.1.1.9 version of the JRF binaries in instances deployed on it. Since the 16.4.5 release (December, 2016), JCS-SaaS Extension has used a hybrid approach to support both FMW 11.1.1.7 and FMW 11.1.1.9 JRF components wherein components have both a FMW 11.1.1.7- based oracle_common home and one based on FMW 11.1.1.9. This topology facilitates upgrading the current instances from FMW 11.1.1.7 to FMW 11.1.1.9 during patching by addressing significant changes in the JRF Components (ADF, OWSM, OPSS, and so on) but creates incompatibilities with the current configuration and applications running PS6-based instances, which introduces a degree of risk during the migration process. To provide a safer means of moving instances between FMW 11.1.1.7 and FMW 11.1.1.9, the JCS-SaaS Extension SDK provides these two commands:

• upgrade-service-instance upgrades instances provisioned in release 16.4.5 and earlier and running with FMW 11.1.1.7 JRFs to FMW 11.1.1.9. See Upgrading an Instance from PS6 to PS7.

• downgrade-service-instance reverts the upgrade of instances previously upgraded with upgrade-service-instance. See Downgrading an Upgradaed Instance.

Note:

upgrade-service-instance and downgrade-service-instance replace jrf-migrate-to-ps7 and jrf-revert-to-ps6–introduced in JCS-SaaS Extension version 17.2.3–respectively. While these former commands will still work, we recommend that you use the new commands going forward and reserve the former commands only for when you need to ensure backward compatibility.
