Overview of a 7.1.x
to 7.1.y Upgrade
This section provides an overview of the procedures required to upgrade
your VCX system from one version of VCX software (7.1.x) to a later
version (7.1.y). These procedures upgrade the VCX system to an
operational state. This section assumes the VCX system is successfully
operating at version 7.1.x before you perform the upgrade.
This appendix describes how to upgrade a VCX server by entering
commands at a locally attached console. You can also upgrade a VCX
server remotely by using 3Com Corporation’s Enterprise Management
Suite (EMS). EMS is an SNMP-based client/server application. Refer to the
Enterprise Management Suite User Guide for VCX V7000 Components
for information.
All components in a VCX system must run the same version of VCX
software. This requirement has the following implications:
■ You cannot upgrade or downgrade one component in a VCX system
and not upgrade or downgrade the other system components.
■ If you add a server to an existing VCX system (for example, a branch
office), the VCX components on the new server must be installed with
the same version of the VCX software as the existing components.
CAUTION: 3Com Corporation strongly recommends that you perform
backups of your VCX system on a regular basis, for example, weekly.
These backups should include provisioning database and voicemail
database content.
■ See Chapter 5 for information on backing up the provisioning data
stored in the VCX Authentication and Directory server database.
■ See the IP Messaging Module Operations and System Administration
Guide for information on backing up voicemail and other IP
Messaging data.
■ Also regularly back up the VCX configuration data on each VCX
server. (See Chapter 4
.)
In addition, BEFORE you upgrade your VCX system to a new release,
perform these backups again. If the upgrade fails and you must
downgrade, you can restore data from these backups as part of the
downgrade procedure.
