I have an Xbox one and s and I want to play some of my disc games on the Xbox series s. Do...

I have several disc games for my Xbox One, i am buying a Series S, but how will i pay them on it?

You wouldnt. Xbox Series S can only play digital games so if you want to play them on Series S you would have to repurchase them digitally.

You have names mixed up. There are no consoles named the Xbox One Series S or Xbox One Series X.

The Xbox One/One S/One X all have a disc drive.

The Xbox One S All Digital Edition does not have a disc drive.

The Xbox Series X has a disc drive.

The Xbox Series S does not have a disc drive.

All the consoles can play backward compatible games. The Series S and One S all digital edition can only play games digitally downloaded.

The other consoles can play games from disc and from digitally downloaded,

I hope this clears things up for you.

Thank you for the reply.

The FAQ states the following:

• If you’re playing from disc on Xbox Series X|S, you’ll need to keep the disc inserted to play that game.
  

This implies if I bought a disc and installed on my xbox one, I would require the disc to play on my Series S. However the Series s is discless. I don't understand how a physical disc can state smart delivery for the Series S.

I understand that you want to play disc games on the series S but I think you already know that's not possible..
Series S is an all digital console. A Disc can't be be used on it.
I know what it feels I have some physical copies for old games like FH3, and basically all the forza saga.
I can play the games only on my Series X.

Both consoles are great, but depending what you need you may need to choose between Series S and X

If you have old games and you don't want to buy a Series X your best bet right now to play them is get an Xbox One X or Xbox one S console

I don’t want to buy a new Xbox since I have games and those games I can only play one Xbox or Xbox series x|s

What do you mean by this?

Your digital games aren't permanently tied to one console, so you wouldn't have to buy them again if you bought a Series S. Obviously, you can't play disc-based games on the Series S as it has no disc drive.

But yeah, apart from things like the USB ports, the Series S hardware is completely different to the One S, so even if it was possible to upgrade the hardware of a console, you'd be replacing basically everything anyway.
