The Software Install-Upgrade window provides options to install or upgrade the SBC Application.

SBC supports Upgrade Manager interface, which performs Live Software Upgrade (LSWU) on an HA pair without affecting the SBC services. The Upgrade Manager interface upgrades the SBC application on both active and standby SBCs of the HA pair. This functionality is supported in both ERE and ePSX configuration.

Upgrade Manager interface:

• indicates the progress of current upgrade action, current upgrade state and the percentage of completion.
• allows you to perform a pre-upgrade check at any time when SBC is functional. It also instructs you to proceed with the upgrade or not based on the logs collected during the pre-upgrade checks.
• provides a clear indication of the step which failed during the upgrade process and leaves the SBC in a state where manual intervention is possible to complete the upgrade process. 

It also provides REST interface to external authentic clients and EMS to perform and monitor LSWU.

Complete SBC Application Package files are available on SalesForce Salesforce for download. For more information on how to download the required SBC Application files, refer to Downloading the Software from SalesForceSalesforce.

Once the files uploaded, they are available on Software Install-Upgrade window.
