Upgrade Issues
When upgrading your system to the latest version of, there are four different upgrade types:
• 3.5inch disk upgrade from an OS/2 version
• Network upgrade from an OS/2 version
• Direct connection upgrade
• Version update from an earlier version
With a disk upgrade, the new system can use most messaging system database files from the old system. However, no
customized prompts, messages, voice names, and greetings are available after the upgrade.
A network upgrade from an OS/2 version includes the database files, voice names, and greetings.
With all upgrade types, some switch and integration settings may need to be customized through the Administrator
System settings. See the Installation Guide, your phone system Integration Guide (if applicable to your system), and
the phone system manufacturer’s documentation for details.
Reports of Missing Archived Messages
When performing a version update, which spans several days, archived messages may be deleted if the archive days
limit was reached during the upgrade process. All messages older than the archive days limit will be deleted when the
system is brought back online. To prevent this from happening, tell users to rearchive their messages prior to beginning
the upgrade process.
