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.
HA Upgrade Scenarios 3
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.
Note:
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
