Upgrade Guide
Chapter 1
Getting started
Use this document to upgrade a Business Communications Manager (BCM) or Survivable Remote
Gateway (SRG) system to BCM 4.0 or SRG 1.5 software. Table 1 lists the supported upgrade
paths to BCM 4.0 and SRG 1.5.
The upgrade of a beta version of BCM 4.0 software to the released version is supported by the
Software Update task of Element Manager. Refer to the Software Updates chapter of the BCM 4.0
Administration Guide for information on how to use the Software Update task to perform the
upgrade of your BCM 4.0 beta system to the generally available BCM 4.0 released version.
The hardware for BCM200, BCM400, and BCM1000 systems remains the same as for BCM 3.6
and BCM 3.7. If you have a functional BCM system, there is no need to reinstall your system
hardware before beginning the upgrade.

Survivable Remote Gateway (SRG)
An SRG system uses the same hardware and is based on the same software as a
BCM system (SRG 1.0 is based on BCM 3.6/3.7; and SRG 1.5 is based on
BCM 4.0). When the SRG keycode is applied, only the SRG functionality is
activated. Therefore, the same upgrade process is used to upgrade BCM and SRG
systems.
