Avaya Communication Server 1000E Upgrade
Co-resident Call Server and Signaling Server
In CS 1000 Release 7.5, the Co-res CS and SS does not support an HA
configuration (dual core with either Active or Inactive role). For systems that
require HA configuration, you must deploy a VxWorks-based CS 1000
system.
The following upgrade paths are supported for CS 1000 systems.
• Communication Server 1000E Call Server with Standard Availability
(SA) to a CS 1000 Release 7.5 Co-resident Call Server and Signaling
Server
If you upgrade from a non-CP PM based CS 1000E Call Server, you must
replace your old Call Server hardware with a supported Server and upgrade
the software.
• CS 1000E Signaling Server to CS 1000 Release 7.5 Co-resident Call
Server and Signaling Server
• Meridian 1 Option 11C, CS 1000M, or CS 1000S Call Server to
Communication Server 1000 Release 7.5 Co-resident Call Server and
Signaling Server
• Meridian 1 Option 11C Call Server to CS 1000 Release 7.5 CS 1000E
TDM.
The minimum CS 1000 Release for Small System migration to a Co-resident
Call Server and Signaling Server is Release 23.10
The CS 1000 Release 7.5 Co-resident Call Server and Signaling Server is
supported on CP PM cards, CP MG cards, CP DC cards, and COTS2 servers
running the Linux Base Operating System.
The Co-res CS and SS can run on the CP PM hardware platform introduced
in CS 1000 Release 5.0, however the software changes from VxWorks to
Linux, and a CP PM Linux upgrade kit is required. The CP PM card requires
