To upgrade from the previously installed version of Web Filtering Proxy follow these steps. Please note generally only upgrades from one previous version are supported, i.e. version 2.5 can be upgraded from version 2.4 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 2.4).
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 Wizard 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. On the first step you would need to choose the previous version of the application to import settings from.
Wait till the next step is complete. Note, depending on the number and size of the access logs the import might take a lot of time.
Final step shows the log of the import. It might be helpful if anything goes wrong during update.
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.
Note it might be possible the import wizard will appear stuck and hanging - just let it work until all settings are imported. The delay is usually due to a large volume of access logs collected in the previous version of the product which need to be copied to the new installation directory.
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.
