106 CHAPTER 9: UPGRADING AND MAINTAINING VCX SYSTEMS AND COMPONENTS
■ Upgrading the IP Messaging Software from 6.0x to 7.0
■ Upgrading the SIP Phone Downloader and Boot File Software from
6.0x to 7.0
Upgrading a Multiple
Site Configuration
from 6.0.x to 7.0
This section describes how to upgrade a VCX configuration from version
6.0x to 7.0 where there is more than one regional office and branch
offices present.
These instructions assume a two-region office configuration where the
regional offices use global messaging and the branch offices use local
messaging configurations. When upgrading a region-to-region office
configuration, replication needs to be dropped.
Following this procedure upgrades the VCX system to an operational
state and assumes the VCX system was operational prior to the upgrade
occurring.
Multiple Site Upgrade Order
When upgrading a multiple site configuration keep this order in mind,
which is outlined in more detail in the actual procedure:
■ First, upgrade the replicated regional office VCX data servers.
■ Second, upgrade the regional office IP Messaging servers.
■ Third, upgrade the regional office Call Processing server.
■ Fourth, upgrade the branch offices, starting with any that are hosted
by the primary regional office.
The software upgrade package is provided by 3Com or your authorized
3Com reseller and must be installed using the following sequence of
steps.
1 Untar the upgrade tar file(s) and copy them to the EMS server in the
<EMS_INSTALL_DIR>/software_upgrades/voice/SystemUpgrades
directory. This includes any software for the VCX data server, IP
Messaging server, and/or the VCX call processing server.
2 If you have a replicated system, clear any replication errors before
performing an upgrade, otherwise, go to step 3
.
a From the EMS client explorer tree, for each VCX data server you want
to drop replication from, click 3Com VCX IP Telephony Server.
