Post-Upgrade Checklist

1You must clear your web browser cache before you login to the SBC SWe Lite.

Perform a backup of your data on the new SBC SWe Lite version. Sonus recommends that you rename the backup filename to indicate the current software version and build number.


Ensure there are no new alarms generated after the upgrade. In the event of finding new alarms, address what is causing them.
