Performing the Upgrade - For Microsoft Azure Deployments

The Azure-based instance of SBC SWe Lite is initially acquired and deployed via Azure Marketplace. For a subsequent upgrade to the SBC SWe Lite, go to the Ribbon Support Portal - Download Center to download the latest compressed software image bundle (.zip ) that contains the upgrade file and upload it onto the SBC SWe Lite. Software upgrades are available for Ribbon customers current on maintenance. (This upgrade offering is established upon initial license purchase from Ribbon.)

Follow these steps for upgrading to the latest Azure instance of SBC SWe Lite:

Performing the Upgrade - For On-Premises Deployments
