The following in-service (hitless) upgrade and rollback paths are supported by both the Oracle Enterprise Communications Broker:

Table 1-1 Upgrade Paths

From Version To Version
P-CZ4.0.0 P-CZ4.1.0
P-CZ3.3.0 P-CZ4.1.0
P-CZ3.3.0 P-CZ4.0.0
P-CZ3.2.0 P-CZ3.3.0

Note:

If you want to rollback or downgrade, ensure that you backup the configuration before performing the upgrade. After rollback, manually restore the saved backup.

All paths require that you meet recommended resource requirements before you upgrade. If necessary, upgrade to supported path versions prior to your upgrade.

When upgrading to P-CZ 4.1.0 release from a release older than the previous release, read all intermediate Release Notes documents for notification of incremental changes.
