This guide provides step-by-step instructions for upgrading a Digital Broadband 
Delivery System (DBDS) to System Release (SR) i4.2.2.   

The upgrade to SR i4.2.2 features the Solaris Live Upgrade. Through use of the Live 
Upgrade, engineers can upgrade the system to SR i4.2.2 without having to shut 
down the system processes until activation of the new system software. 

Sites that upgrade to SR i4.2.2 must currently support SR i4.2.1 or SR i4.2. 

The upgrade to SR i4.2.2 is to be completed from within a maintenance window that 
usually begins at midnight. Upgrade engineers have determined that a typical site 
can be upgraded within one maintenance window. The maintenance window should 
begin when you stop system components in Chapter 2. 

Interactive services will not be available during the maintenance window. 

This guide is written for field service engineers and system operators who are 
responsible for upgrading an existing DBDS to SR i4.2.2.  

Please review this entire guide before beginning the installation. If you are 
uncomfortable with any of the procedures, contact Cisco® Services at 1-866-787-3866

Important:  Complete all of the procedures in this guide in the order in which they
