Can I change credit cards in the same bank without closing the original "account"?

So basically I got a scene visa card right when I turned 18, and it's my oldest credit card. I don't want to close it because I know that the age of accounts is something that matters for your credit score, but I don't really have any need for scene points. Is there a way for me to get a different credit card from Scotia without them closing the old account as far as my credit score is concerned? I already have a second card, and I don't really want to add a third one to the equation.

Hopefully this makes sense, and thank you!
