Install PC - Upgrade DECT Messenger

Introduction

Since the introduction of DECT Messenger, several commercial versions

have been released: 1.0, 2.0, 2.8, 2.9, 2.9.10, 3.0, and now 4.0.

There are two major items involved in upgrading to a new release.

• updated database design

•

prerequisites

Generally speaking, new releases typically introduce new functionality and

handle known maintenance issues of previous releases.

Conﬁguration database

DECT Messenger stores its configuration in a centralized configuration

database called Messenger_CFG.MDB residing in C:\SOPHO

Messenger@Net\Mdb.

It is important to not lose the DECT Messenger configuration database

during the upgrade process. If the configuration database is lost, your

configuration is replaced by a default configuration of 4.0 and results in a

loss of configuration.

Instructions are given on how to preserve other settings and resources,

for example the logging file, National-Instruments configuration files, and

so on.

When eKERNEL starts, eKERNEL analyzes Messenger_CFG.Mdb and, if

necessary, applies changes to the layout of the database. This can include

adding tables, adding fields, and altering attributes.

Recommended approach

The recommended approach to upgrade to a new release of DECT

Messenger is to consider the upgrade as installing a new system, but

taking a backup first of the items needed in order not to lose configuration

data.
