Upgrading a Multiple | This section describes how to upgrade a VCX configuration from version |
| Site Configuration | 7.0 to 7.1 where there is more than one regional office and branch |
| from 7.0 to 7.1 | offices present. |
| EMS does not allow individual component upgrades without first |
| installing a new version for switchover. However, individual component |
| upgrades can be performed without first installing a new version for |
| switchover through the CLI interface. |
| These instructions assume a |
| regional offices use global messaging and the branch offices use local |
| messaging configurations. When upgrading a |
| configuration, replication needs to be dropped. |
| Multiple Site Upgrade Order |

| 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. |
