306 APPENDIX D: DOWNGRADING VCX SERVER SOFTWARE
Note that the downgrade procedure does not remove VCX version 7.1.y
software from your VCX system.
Downgrading a
Single-Site System
(7.1.y to 7.1.x)
This procedure describes how to downgrade a pair of VCX servers
running these software configurations:
■ IP Telephony and Messaging
■ IP Telephony only
■ IP Messaging only
Switch VCX Version
To switch the VCX version, perform the steps in this section, first on the
primary server and then on the secondary server.
1 Log in as root and enter this command:
vcx-switchversion --manual 7.x
Example: vcx-switchversion --manual 7.1.0c
The vcx-switchversion command:
■ Stops VCX services
■ Changes a link to point to the requested VCX version
■ Issues a warning that databases must be restored
CAUTION: Do not reboot the system or restart VCX services until
databases have been restored. The VCX 7.1.x version has been selected
but the databases still contain 7.1.y versioned data. This combination will
not operate successfully.
2 Update the pointer to the configuration file using this command:
SetConfigFile /opt/3com/VCX/conf/VCXConfiguration.xml
Stop Database Replication
If the server is running IP Telephony and IP Messaging server software or
IP Telephony server software, you must stop database replication.
CAUTION: If the server is running IP Messaging server software do not
perform the steps in this section.
