Cisco Headend System Release 2.5 Release Notes

4022291 Rev C 

This section contains information that can help system operators plan the upgrade to 
SR i4.2.2. 

 

Note these important upgrade requirements: 

 

Systems that upgrade to SR i4.2.2 must currently be operating with system 
software from  SR i3.0.o.x, SR i4.2.0x, or later. The upgrade software is contained 
in a DVD due to significant changes contained in SR i4.2.2 and other time saving 
factors. Rollback procedures are included in the DVD Upgrade Installation 
Instructions for System Release i4.2.2 in the event that the upgrade is unsuccessful. 

 

Our field service engineers or the system operator must have already installed 
the DNCS Utilities software onto the DNCS and should have already run the 
pre-upgrade checks to ensure system compatibility with SR i4.2.2 DVD upgrade 
requirements. Refer to DBDS Utilities Version 6.1 Installation Instructions and 
DNCS Utilities User Guide (part number 4020695) for instructions on installing 
and executing the DNCS Utilities. 

Important: You can now use Live Upgrade with the installation DVD. Through the 
use of Live Upgrade, engineers can upgrade without shutting down the system 
processes until you activate the new system software. 

 

The actual upgrade to SR i4.2.2 must be completed within a single maintenance 
window that usually starts around midnight. A few pre-upgrade procedures, 
consisting mainly of system checks, backups, and various operations upon the 
metadevices of the DNCS, can be completed before the maintenance window begins. 

Our engineers have determined that a typical site can be upgraded within one 
maintenance window. See Scheduling Requirements (on page 10) for additional 
details. 

 

Interactive services will not be available during the maintenance window.
