Live Software Upgrade (LSWU)

LSWU allows a user to upgrade the

Spacevars
0product
 application software on HA pairs without impacting service (dropping calls). This is mainly recommended for HA SBC systems. You can also perform a LSWU on the 
Spacevars
0product
 EMA and in 
Spacevars
0product
 EMA Platform Mode. Refer to Live Software Upgrade using CLI and System Administration - Software Install-Upgrade for more information.

Non-Live Software Upgrade (Non-LSWU)

The non-LSWU upgrade process requires taking the SBC system offline to perform an application upgrade. This refers to upgrading the

Spacevars
0product
 application in a standalone or HA configuration using EMA Platform Mode. Refer to Upgrading SBC Application using EMA Platform Mode for more information.


Info
titleNote

Once the upgrade is complete, rediscover the SBC from the EMS, if present, and edit any attributes that may have been modified post-upgrade. Attributes are listed under the EMS page Register an SBC Core Node.
