11Upgrade GuideChapter 2Pre-upgrade activitiesBefore you attempt to perform the upgrade, review the following prerequisites carefully todetermine whether your system is compliant, and perform the indicated tasks to prepare yoursystem for the upgrade process.If you are unable to correct any issues, contact technical support within your organization forinformation on resolving the issues.Important information to note before attempting this upgradeThis section provides notes, warnings, and information that is critical to the upgrade.• New administrator account is nnadmin: After the upgrade is complete, the only accountavailable on the BCM 4.0 system is the default administrator account, which is nnadmin andthe password is PlsChgMe!.• BCM 3.6/3.7 backup required: It is important to have a complete and current backup of yourBCM 3.6/3.7 system in case there is a failure of the upgrade. This backup can be used torestore 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 driveis repartitioned. This removes all data including data that is not recognized as part of theBCM 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. Allcomponents that exist on the hard drive are replaced as needed by the corresponding BCM 4.0components.• Voice mail and telephony data are preserved: Telephony data and personal voice mailmessages 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/ISDNtelephones. Since Companion is not supported in BCM 4.0, all former Companion DNs in therange appear as ISDN DNs. Also, all the data on the former Companion DNs is set to defaultvalues.• Hospitality services: The value for Retry Interval is not automatically changed to correspondwith BCM 4.0 parameters. In BCM 3.7, the values for Retry Interval are 2–9 inclusive; theselected value is retained when upgrading to BCM 4.0. However, if you change the RetryInterval 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 startthe Upgrade Wizard until the upgrade is complete, approximately 60 to 90 minutes under idealconditions. The system services are down during that period, so ensure that you notify yourusers of the outage. Your system will be fully functional once the upgrade is complete, theclient applications are upgraded, and the services are restarted, with the exception of the itemsthat are no longer supported under BCM 4.0.
