Introduction
This chapter contains procedures that must be completed before you
begin the actual upgrade to SR 2.8.1/3.8.1/4.3.1. These pre-upgrade
procedures consist mainly of system checks, backups, and various
operations upon the metadevices of the DNCS.
The actual upgrade to SR 2.8.1/3.8.1/4.3.1, 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
2.8.1/3.8.1/4.3.1 upgrade.

Before You Begin
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 CD-ROM containing your
current version of Application Server software. You may need this
CD if you ever have to roll back to the previous system release.
