Upgrade Guide
Chapter 2
Pre-upgrade activities
Before you attempt to perform the upgrade, review the following prerequisites carefully to
determine whether your system is compliant, and perform the indicated tasks to prepare your
system for the upgrade process.
If you are unable to correct any issues, contact technical support within your organization for
information on resolving the issues.
Important information to note before attempting this upgrade
This section provides notes, warnings, and information that is critical to the upgrade.
• New administrator account is nnadmin: After the upgrade is complete, the only account
available on the BCM 4.0 system is the default administrator account, which is nnadmin and
the password is PlsChgMe!.
• BCM 3.6/3.7 backup required: It is important to have a complete and current backup of your
BCM 3.6/3.7 system in case there is a failure of the upgrade. This backup can be used to
restore your BCM 3.6/3.7 system. Then you can attempt the upgrade again.
• Hard drive will be erased: Each partition of the entire hard drive is erased and the entire drive
is repartitioned. This removes all data including data that is not recognized as part of the
BCM 3.6/3.7 software and all logs and on-box backups. This affects the entire hard drive,
including documentation, client applications, and the maintenance operating system. However,
operational and configuration data (such as voice mail and telephony data) are preserved. All
components that exist on the hard drive are replaced as needed by the corresponding BCM 4.0
components.
• Voice mail and telephony data are preserved: Telephony data and personal voice mail
messages are preserved during the upgrade even though the entire hard drive is erased.
• ISDN/Companion DNs: There is a specific range of DNs reserved for the Companion/ISDN
telephones. Since Companion is not supported in BCM 4.0, all former Companion DNs in the
range appear as ISDN DNs. Also, all the data on the former Companion DNs is set to default
values.
• Hospitality services: The value for Retry Interval is not automatically changed to correspond
with BCM 4.0 parameters. In BCM 3.7, the values for Retry Interval are 2–9 inclusive; the
selected value is retained when upgrading to BCM 4.0. However, if you change the Retry
Interval setting in BCM 4.0, the acceptable values are 2, 4, 6, 8.
• Services are unavailable during upgrade: Your system will be out-of-service once you start
the Upgrade Wizard until the upgrade is complete, approximately 60 to 90 minutes under ideal
conditions. The system services are down during that period, so ensure that you notify your
users of the outage. Your system will be fully functional once the upgrade is complete, the
client applications are upgraded, and the services are restarted, with the exception of the items
that are no longer supported under BCM 4.0.
