Upgrading CMS to the High Availability Option 

describes CentreVu Call 

Management System (CMS) upgrade procedures required to add a new 
CMS server to an existing CMS system in order to create a CMS High 
Availability (HA) system. 

The CMS servers used in an HA system must have the same CMS version 
and base load number. If the original server has a different CMS version from 
the new server being added to the system, upgrade of the original server 
must be performed through a Lucent Speed Centre facility.

Two CMS servers to be incorporated into an HA system must be installed 
with the same version (R3V8 or later) and base load of the CMS software. In 
many, if not most cases, the new HA systems will consist of an existing CMS 
installation  combined with a newly purchased CMS server.  

In the procedures that follow, the two CMS servers incorporated into the 
system are referred to as follows:

the CMS server that is already installed onsite is referred to as the 
“original server” 

the server purchased by the customer to enable the HA option is 
referred to as the “new HA server”.

In terms of the installed CMS software, one of the following conditions will be 
true at the beginning of the upgrade:

a. the CMS servers have the same CMS version and base load

b.the original server has the same CMS version as that installed on 

the new HA server, but the base loads are different 

c. the original server has an earlier version of CMS than that 

installed on the new HA server
