170 APPENDIX A: UPGRADING VCX SERVER SOFTWARE FROM V7.0 TO V7.1
■Multi-site systems that include servers at regional offices and
servers at branch offices that use global or local IP Messaging
■A pair of Global Voicemail Central Servers (GVCS) to enable Global
Voicemail Integration on an entire IP Messaging system
A GVCS coordinates mailbox creation and mailbox updates on
regional and branch office IP Messaging servers. The version 7.0 to
version 7.1 upgrade procedure allows you to enable Global
Voicemail Integration on servers running IP Messaging software.
However, you must install IP Messaging software on a GVCS, and
then set up the GVCS through the IP Messaging administrator
configuration interface before enabling Global Voicemail
Integration on regional and branch office IP Messaging servers.
Refer to the IP Messaging Module Operations and System
Administration Guide for more information and for configuration
options.
■Call server software
Supported on multi-site systems that include servers at regional offices
with or without branch offices
■Call Records server software
Supported on multi-site systems installed on a single server for
regional offices with or without branch offices
■Authentication and Directory server software
Supported on multi-site systems that include servers at regional offices
with or without branch offices
You should upgrade each server from a locally attached console. The
upgrade procedure includes a reboot of each upgraded server. If you
perform an upgrade remotely (using a secure shell client, for example),
you will be logged out when the reboot occurs. When you log back in, it
may not be apparent that the upgrade has completed. If you enter
commands before the upgrade has finished, the upgrade will fail.
