▄  VPC-VSM System Administration Guide, StarOS Release 19 

Updating StarOS on an ICSR-configured VPC-VSM instances requires performing an off-line update of each instance 
while it is standby mode. Traffic disruption is minimal since an active instance will be handling call sessions while the 
standby instance is being updated. 

The general upgrade sequence is as follows: 



 

Download the StarOS software image and copy/transfer it to a location accessible by both instances. 



 

Save the currently running configurations on both instances. 



 

Update the standby backup instance first. 



 

Initiate an SRP switchover from the active primary instance to make the standby backup instance active. Initiate 

the switchover by shutting down the HSRP interface being monitored by SRP. 



 

Update the standby primary instance. 



 

Initiate an SRP switchover from the active backup instance to make the standby primary instance active. Initiate 

the switchover by shutting down the HSRP interface being monitored by SRP. 

The four-part flowchart below shows a more complete view of all the procedures required to complete the StarOS 
upgrade process.
