Upgrading Branch
Offices
This section describes how to upgrade branch offices. Each branch office
is associated with a regional office.
As noted in Upgrading a Multi-Site VCX System with Branch Offices,
multi-site VCX systems can be categorized by the method used to
implement messaging: global messaging, local messaging, or Global
Voicemail Integration.
The procedures in this section are based on a multi-site VCX system that
includes two regions (Region 1 and Region 2). For this example system,
the branches in Region 1 use local messaging, and the branches in
Region 2 use global messaging.
■A branch that implements local messaging runs IP Telephony and IP
Messaging server software. Because this type of branch office includes
IP Messaging services, you can enable Global Voicemail Integration on
the branch.
■A branch that implements global messaging runs IP Telephony server
software. The IP Messaging server software running on a regional
server provides messaging services for the branch. Because this type of
branch office receives its IP Messaging services from a regional IP
Messaging server, you cannot enable Global Voicemail Integration on
the branch. In this case, you must enable Global Voicemail Integration
on the regional server.
All upgrade commands are executed locally at the console.
CAUTION: When upgrading a multi-site VCX system, upgrade the
regional servers before upgrading the branch servers. If you upgrade the
branch servers first, the database schema on the branches may not match
the schema version on the region causing database replication failure.
To upgrade the branch offices in Region 1 (local messaging):
1Log in to the first branch office server as root.
2Obtain a copy of the vcx-all-7.1.xc.tar software upgrade file and
place it in the /opt/installtemp directory on the branch office server.
The variable x indicates the version of VCX software (for example,
