This is a detailed guide on how to upgrade an IP.Board 3.4 app. For the purposes of this guide, I'll be using the Portal application as an example. But these instructions can be used for other applications. Obviously replacing the references to Portal to the other applications name.
Download the application and unzip it's contents into a folder on your desktop if needed. Most applications will have a basic folder structure like this. With the applications tar file and the readme or instructions file.
Open your Admin CP. In your browser and navigate to the System Tab then on the left side menu and then the Applications menu. At the very bottom you'll notice the "Out of date applications" section. On the same row as the application you'll notice an option to "Upload a new version", click it and find the applications tar file you just unzipped onto your desktop. Once your ready, click the Install button to start the import. The application upgrade will then run through the upgrade and you'll see several redirects until it's fully upgraded.
Step Three (Manage)
After you've installed it, depending on the type of application it is. You may notice a new tab on the front end of your forum or even more menus in the admin cp of your forums. This is how you'll view and setup this application.
Step Four (Widgets)
Applications now come with the ability to add widgets to your forums. If your application does have a widget available, Open your forums home page and locate the "Manage Blocks" icon on the center left hand side of your forums. Clicking this will load a side menu with all the available application widgets, locate the widget for the application your installing and then drag and drop it to what ever widget area position is available..
