318 APPENDIX D: DOWNGRADING VCX SERVER SOFTWARE
The downgrade procedure does not remove VCX version 7.0 software
from your VCX system.
If you have configured a VCX server running version 7.0 software for
RAID operation, you cannot downgrade that server to version 6.0
software. VCX servers running software versions prior to the 7.0 release
do not support RAID configuration. If a VCX server enabled for RAID
operation must be downgraded to a software version prior to 7.0, the
server must be rebuilt. Contact your 3Com representative.
Downgrading a
Single-Site System
This procedure describes how to downgrade VCX single-site systems.
Single-site VCX systems can have either two servers or four servers.
■In a two-server configuration, each server runs IP Telephony server
software and IP Messaging server software.
The downgrade steps described in the following sections must be
performed on each server.
■In a four-server configuration, one pair of servers runs IP Telephony
server software; the second pair of servers runs IP Messaging server
software.
The downgrade steps described in the following sections must be
performed on each server running IP Telephony server software. For
servers running IP Messaging server software, the database
maintenance steps are not required.
Switch VCX Version
To switch the VCX version, perform the steps in this section on each
server in the single-site system.
■In a two-server configuration, perform the steps first on the primary
server and then on the secondary server.
■In a four-server configuration, perform the steps first on the primary IP
Telephony server and then on the secondary IP Telephony server. Then
perform the steps first on the primary IP Messaging server and then on
the secondary IP Messaging server.
1Log in to the server as root user.
2Enter the following command:
vcx-switchversion --manual 6.x
For example, to downgrade to VCX version 6.0.2.c, enter:
vcx-switchversion --manual 6.0.2c
