Change from phpbb3 to InVision

As title, is this possible please?

I decided to try phpbb3 as it had been recommended to me, so downloaded it and have been attempting to set it up, but I have been used to InVision and for ease of use and quickness in wanting to set up a forum, I want to revert to InVision. What happens with the name I have chosen for the phpbb3 forum, I don't want to lose that.

Thanks in advance

I never tried this before,but I think this would work:

Administration Panel=>Display=>Styles=>Choose a theme=>Version=>General=>
You'll see this screenshot:

Choose Invision=>Save

Whoooo hoo

Thank you very much, I might have a clue what I am doing now LOL

Fyi when you change version you only change looks/style/theme.
