I'm not sure the right name is – but I'm just wondering whether there is available some sample site provided by Invision where we can open an admin account and have a look at the adminCP et cetera to try and begin a little understanding of the layout and differences et cetera.

Thanks

Take a gander over at:

A free trial is your best bet for something completely hands off. Otherwise, as you're self-hosted, you can create your own test install.

Thanks again for the advice to use the free trial. It's very helpful – mainly reassuring because I see a great familiarity in the backend and I can see that it's not going to be as difficult as I imagined.
