Cautions and Disclaimers

This document shows how to update from DSS V8.0.4 to DSS V8.1
Please note that the following instructions only apply to DSS Baseline. If you are using a customized version of DSS, that will be a case-by-case discussion if you want the update. Please consult Tech Support for more information
Only Baseline DSS Express and DSS Professional can be upgraded in this way
Because DSS is Server-client structure, you need to upgrade DSS Server before upgrading DSS Client

Step by Step Instructions

Part 0: Check the Current DSS Version

Log into DSS Client and select [About]

Here you can see the DSS Server Version. Make sure the Installation Package is later than this version.

Part 1: Back up the current system Database – this will prevent data loss in case of update failure

1. Go to the Home menu of DSS – Select [Backup and Restore]

2. Click on the folder icon to select the directory where you want to save the backup file. Then, click on [Backup Now]

3. Insert the Login Password of DSS Client and Encryption Password twice.

In the end, Click on OK and DSS will export the Backup File automatically.

4. When DSS finishes exporting the Backup File, you will receive a prompt message saying Backup successful

9. DSS Package will automatically detect the older version and overwrite the current directory. Click on [OK] to continue

10. Select [Agree] and click on [Next]

!Note: It may take some time for SMC Service to start, depending on the hardware of the Server
