updating plugins

I need to update a plugin to 4.8 from 4.7
The plugin is to add support for a logitech g27 Steering wheel.
If anyone can tell me how to go about updating it please help me.
The link to the plugin:

Basically hit compile and see which errors occur and go from thereā€¦ I suspect that its not too hard and there are probably enough topics already for the most common errors that you will find.
