To upgrade from the previously installed version of Web Filtering Proxy follow these steps. Please note only upgrates from one previous version are supported, i.e. version 1.5 can be upgraded from version 1.4 only, not from any earlier version.
Uninstall Previous Version
First step is to uninstall the previous version of the application using standard Microsoft Windows Add/Remove programs dialog. After uninstall, all settings of the application are left in
C:\ProgramData\Diladele\WebProxy\N.N folder (where N.N symbolizes actual version, like 1.3).
Install New Version
Now install the new version of Web Filtering Proxy as usual.
The next step is to automatically import the settings from the previous version of the application. To do that, open Admin UI and select Advanced Settings / Upgrade Manager as shown on the following screenshot. The Admin UI will try to import all information from
C:\ProgramData\Diladele\WebProxy\N.N folder into installed version.
If import is successful you will see the following confirmation dialog.
In case of failures an error dialog will be shown. For example, like this one.
After successful import, close and reopen the Admin UI and click Apply All Changes and Restart Service button.
Remove Old Settings
The last step is to manually remove the old settings of the application by deleting the C:\ProgramData\Diladele\WebProxy\N.N folder.
