12 Software Upgrade
This section provides information about how to upgrade your Oracle Communications Session Border Controller software image. Note that proprietary Acme Packet hardware is normally delivered with an operational image ready to run. Your deployment, however, may require a different version that what was delivered, making software upgrade a required step in platform preparation.
The Check Upgrade Readiness Command
The SBC provides you with the ability to examine system components and status to determine whether an upgrade can occur seamlessly. If not, the system provides you with information that describes changes you should make prior to attempting an upgrade. Review the output of this command three times during an upgrade cycle:
- Run the check-upgrade-readiness command before any software upgrade. Examine the command output to identify and resolve any potential upgrade issues.
- Also note that the system runs the check-upgrade-readiness command automatically upon the first reboot after a software upgrade. If the system finds significant issues after running the command, it may revert back to booting with the previous software version.
- Run the check-upgrade-readiness after upgrade to check for any potential operational issues.
Note that the verify-config command can also provide important system status information that can assist you during an upgrade.
