Downgrading Regional Authentication and Directory Servers
If a downgrade is required on a regional Authentication and Directory
server, the procedure is the same as that described in
Single-Site System (7.1.y to 7.1.x)
with one difference. Each
Authentication and Directory server contains a database schema for each
region.
For
each
schema, you must:
■
Drop database replication
■
Restore the database from the backup file
■
Reestablish database replication
Downgrading Regional IP Messaging Servers
If a downgrade is required on a regional IP Messaging server, follow the
procedure described in
Downgrading a Single-Site System (7.1.y to 7.1.x)
Downgrading Call Servers
To downgrade a pair of Call servers, perform these steps, first on the
primary server and then on the secondary server:
1
Log in as
root
and switch the VCX version using 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
Switch operating system version
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
