Downgrading from 7.1 to 7.0 293
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.
Downgrading from
7.1 to 7.0
Follow the procedures in this section to downgrade your VCX system
from version 7.1 to 7.0.
Important
Considerations
Before performing a downgrade, keep these considerations in mind:
■ Downgrades are typically performed for one of the following reasons:
■ You have successfully upgraded your VCX system but want to
revert to the previous version of VCX system software.
■ During a VCX system upgrade, one component fails to upgrade
and want to revert to the previous version of VCX system software.
If a component fails to upgrade, contact your 3Com Support for
assistance before proceeding.
■ To use the downgrade procedures in this section, your VCX system
must have previously been successfully running version 7.1. The
downgrade procedure does not “back-port” any configuration or
database modifications you might have made while running version
7.1. Following this procedure restores the VCX system to the
operational state it was in prior to the upgrade occurring.
■ If an upgrade at a regional office is unsuccessful, contact your 3Com
Support for assistance and downgrade the regional office servers. Do
not upgrade any branch office servers that are associated with that
regional office until the regional office upgrades are successful.
■ The database schema version on a branch office server must match
the schema version on the regional office Authentication and
Directory server. After a successful upgrade of a regional office, if an
upgrade of any branch office server is unsuccessful, contact your
3Com Support for assistance and downgrade that branch office
server.
