Downgrading from
7.0 to 6.0
Follow the procedures in this section to downgrade your VCX system
from version 7.0 to 6.0.
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 6.0.x.
■ The VCX system supports two operating system images. If the
upgrade required installation of a new VCX operating system version,
then the downgrade must revert to the previous installation.
■ This downgrade procedure assumes the VCX version 6.0 system
databases were backed up before the upgrade to version 7.0 was
performed. These version 6.0 backups will be restored as part of the
downgrade procedure.
■ The downgrade procedure does not “back-port” any configuration or
database modifications you might have made while running version
7.0. 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.
■ The person performing the downgrade should be trained in VCX
operation and procedures, and be familiar with VCX terminology.
