312 APPENDIX D: DOWNGRADING VCX SERVER SOFTWARE
Downgrading the Call Records Server
The Call Records server is a stand-alone server (it has no secondary
server). To downgrade a Call Records server, perform these steps:
1 To switch the VCX version, 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
3 If necessary, switch to the previous version of the operating system.
The upgrade from 7.1.x to 7.1.y may or may not have required the
installation of a new VCX operating system version. This step describes
how to determine if a new operating system version was installed and if
so, how to revert to the previous version.
The examples in this step use the assumption that upgrading from version
7.1.x to 7.1.y changed the operating system version from 4.2.0 to 4.2.1.
a Log in as root.
b To determine which operating system versions are available, enter this
command:
vcx-os-query
The output from this command appears:
Example:
OS Version Partition Label Status
A 4.2.0 /dev/hda2 /A
B 4.2.1 /dev/hda3 /B active
The operating system versions that you see may vary from the example
shown.
