20 Chapter 3 Upgrading to BCM 4.0 and SRG 1.5
N0060597N0060597
Upgrading an SRG 1.0 system to SRG 1.5
The Survivable Remote Gateway 1.0 system is a peripheral of the Communication Server 1000
(CS 1000) but leverages the BCM200/400 core software to act as a remote gateway for the Main
Office. Because of this dependency, the upgrade path for SRG 1.0 to SRG 1.5 leverages the BCM
4.0 Upgrade Wizard and upgrade process but requires the unique SRG 1.0 to SRG 1.5 upgrade kit
(NTDU98AA) that includes the SRG 1.0 to SRG 1.5 authorization code.
The upgrade method for SRG 1.0 to SRG 1.5 is shown in Figure 1.
Figure 1 SRG 1.0 to SRG 1.5 upgrade method
SRG 1.0 systems require the SRG 1.0 to SRG 1.5 authorization code. The BCM 3.6, BCM 3.7, or
BCM 4.0 authorization code will not ensure that system is properly enabled for SRG 1.5.
Performing the BCM 4.0 and SRG 1.5 upgrade
Once the Upgrade Wizard is started, the upgrade process takes approximately 60 to 90 minutes to
complete under ideal conditions; some systems may perform the upgrade faster or slower. The
system services are down during that period, so ensure that you notify your users of the outage.
If you encounter condition message during the upgrade, refer to Appendix A, “Troubleshooting,”
on page 39.
You are now ready to start the upgrade.
Warning: Your system will be out-of-service once you start the Upgrade Wizard
until the upgrade is complete.
Warning: Do not disturb the upgrade process once it starts as this may lead to upgrade
issues, even though the upgrade process has features to minimize the chance of data loss.
