This chapter contains procedures that must be completed before you 
begin the actual upgrade to SR 2.8.2/3.8.2/4.3.2. These pre-upgrade 
procedures consist mainly of system checks, backups, and recording 
various system configuration parameters. 

The actual upgrade to SR 2.8.2/3.8.2/4.3.2, including some of the 
procedures in this chapter, must be completed while within a 
maintenance window. Some of the procedures of this chapter, 
however, can be completed before the maintenance window begins. 
See When to Complete These Procedures (on page 3), for a list of those 
procedures that can be completed before the start of the maintenance 
window. 

Important:  Do not remove any third-party applications files from the 
DNCS or change any of their settings before performing the SR 
2.8.2/3.8.2/4.3.2 upgrade. 

Before you begin the upgrade, attend to these two matters: 

 

Call Cisco Services and open an Upgrade Tracking Case. 

 

Verify that you have easy access to the Maintenance CD containing 
your current version of DNCS server software. You may need this 
CD if you ever have to roll back to the previous system release.
