6 Business Communications Manager 2.5 Upgrade

P0987357 02

• We strongly recommend that you use a computer that is within the same subnet as the

Business Communications Manager system that you are upgrading.

• You must know how to share folders. If you use Windows 95, 98 or Me, you must enable file

sharing. Refer to your Windows system documentation for how to share folders.

For VoIP Trunking

• Check the VoIP Remote Gateways that are configured on the Business Communications

Manager 2.0.3 system. The Business Communications Manager system allows Remote

Gateway names that are a maximum of 15 characters. If you have any Remote Gateways with

names that are longer than 15 characters, or that contain spaces, rename the Remote Gateways

so they are a maximum of 15 characters long and do not contain spaces. To rename the

Remote Gateway, in Unified Manager remove the Remote Gateway and re-enter the Remote

Gateway with the modified name.

For voicemail

• If you change the time zone setting for the Business Communications Manager system, all

voicemail messages stored before the time zone change will be inaccessible. It is highly

recommended that you select the time zone as one of the first items configured on the Business

Communications Manager and that you do not change it. If it is necessary to change the time

zone, notify subscribers to delete all stored messages in their mailboxes. You must reboot the

Business Communications Manager system after you change the time zone. This information

applies to Business Communications Manager 2.0.3 and 2.5 systems.

You are now ready to start the upgrade. The upgrade can take approximately two to three hours.

Note: A backup of the core telephony configuration is performed during the upgrade

process. This backup is used during the upgrade to restore the core telephony

configuration, if necessary. This backup can be used on BCM systems that have been

upgraded from BCM 2.0.3 to BCM 2.5 but it cannot be used on systems that were

purchased with BCM 2.5 software.
