7-4 INSTALLING TELEVANTAGE

Upgrading vs. installing for the first time

Q If you are upgrading from a previous version of TeleVantage, go to the next section.

Q If you are installing a new TeleVantage system, go to “Installing a TeleVantage system

for the first time” on page 7-8.

Preparing for an upgrade __________________________________

The information in this section applies to all upgrade paths, no matter what version of

TeleVantage you currently have installed.

Important:

Do not under any circumstances uninstall TeleVantage Server or Microsoft

MSDE/SQL Server. If you uninstall either one, you will lose your TeleVantage database and voice

messages. The TeleVantage installation program preserves your earlier TeleVantage Server

configuration, including voice messages and prompts. If you follow the instructions in this manual,

you will not lose any data when you upgrade.

Scheduling an upgrade

If you are upgrading the live telephone system at your company, you must schedule the

installation after business hours. The process of installing TeleVantage can take more than two

hours. It can take significantly longer if you must configure and test T1, E1, BRI, or VoIP

trunks. During this time, your telephone system will be offline and unavailable.

Backing up the TeleVantage database and voice files

Important: The upgrade is one-way, and cannot be uninstalled. To recover to a previous

version, you will need to restore the entire PC image to the same version of TeleVantage that you

were running previously according to the following instructions.

To maintain the integrity of your existing TeleVantage system and ensure a successful upgrade,

back up your entire system—including the TeleVantage database and voice files—to a safe

location off the TeleVantage Server PC. By backing up your system, you will be able to

reconstruct your current system if you need to recover to the version of TeleVantage that you

were running previously. Backing up an existing TeleVantage system may take an hour or more,

especially if there are many voice messages stored in your database.

To backup the TeleVantage database and voice files, perform an offline backup according to the

instructions in Chapter 12 of Administering TeleVantage. Be sure to refer to the copy of

Administering TeleVantage that matches the TeleVantage version of the system that you are

backing up, because the process is different for each version of TeleVantage.

If for any reason you are unable to start the TeleVantage Administrator, you can back up your

files by running the Administrator from the command line. See “Cannot start Administrator to

back up the TeleVantage database” on page B-10.

Note:

You can only restore the TeleVantage database and voice files to a Server that is running

the exact same version of TeleVantage (including service packs and hot fixes) as the Server on

which you performed the backup. For example, you cannot backup a TeleVantage 5.x Server and

restore it to a TeleVantage 6.x Server. This restriction applies to minor releases as well, for

example, 6.0 and 6.1.
