Upgrading to BCM50 2.0 and SRG50 2.0

This section describes the steps to upgrade a BCM50 1.0 system to BCM50 2.0 and a Survivable

Remote Gateway (SRG) 50 1.0 system to SRG50 2.0. The upgrade processes for BCM50 2.0 and

SRG50 2.0 are almost identical. Any differences in the procedures are indicated in this document.

If you have not already done so, read all the instructions in “Pre upgrade activities” on page 9

before you continue with these instructions.

Upgrading an SRG50 1.0 system to SRG50 2.0

The SRG50 1.0 system is a peripheral of the Communication Server 1000 (CS 1000) but leverages

the BCM50 core software to act as a remote gateway for the Main Office. Because of this

dependency, the recommended upgrade path for SRG50 1.0 to SRG50 2.0 leverages the

BCM50 2.0 upgrade process but requires a keycode that includes the SRG feature in addition to

the upgrade feature and any other features required by the system.

Performing the BCM50 2.0 and SRG50 2.0 upgrade

The upgrade process takes approximately 75 minutes to complete under ideal conditions; some

systems may perform the upgrade faster or slower.

Perform the upgrade process in three stages:

• First stage (less than 5 minutes)—the first stage does not affect system services.

• Second stage (40 minutes)—during the second stage, your system is out of service until this

stage of the upgrade is complete and the system reboots.

• Third stage (30 minutes)—the third stage is optional.

If you are upgrading directly from the two CDs, the first CD (CD1) contains the files for the first

and second stages, and the second CD (CD2) contains the files for the optional third stage.

Perform the upgrade process through Element Manager. For more information about Element

Manager, see the Administration Guide or the online Help within Element Manager. See Figure 1.

If you encounter problems during the upgrade, see Troubleshooting on page 25. If the upgrade

does not complete successfully, contact technical support for assistance in identifying the cause of

the failure.

Warning: Perform a data backup before you start the upgrade process.

Perform a backup of your system before you attempt the upgrade. Store the information

off the hard disk of the system and off the management computer. This ensures that you

can restore your system if the upgrade is not successful after you run a level 2 reset.
