Downgrading a
Multiple-Site System
(7.1.y to 7.1.x)
The examples in this procedure 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.
1 Log in as root.
2 To determine which operating system versions are available, enter this
command:
vcx-os-query
The output from this command appears:
OS Version
A 4.2.0
B 4.2.1
The operating system versions that you see may vary from the example
shown.
The order of the A and B versions may be reversed depending on the
upgrade history of the system.
When you are downgrading, use the earlier of the two operating system
versions in this command:
vcx-os-switch 4.2.0
To confirm that you have selected the operating system version that you
want, repeat the
"selected" appears in the Status column for the version that you want.
Example:
OS Version
A 4.2.0
B 4.2.1
Reboot the Server
Reboot the system using this command:
reboot
When the system reboots, it starts VCX 7.1.x services.
For VCX systems that are installed at multiple sites, upgrades and
downgrades must be performed using a specific sequence of servers, as
described in this section.
CAUTION: Back up all databases before beginning an upgrade.
