Hello Cincisquirtle,my name is Marvina, I will be happy to help you.

The short answer is yes, you need to transfer the licenses from your Xbox 360 to your Xbox Series X in order to access downloaded content (DLC) for your Xbox 360 games.

To transfer licenses, follow these steps:

Sign in to your Microsoft account on your Xbox Series X.

Go to "Settings" > "System" > "Licenses".
Select "Transfer licenses to this console."
Follow the instructions on the screen.

This process will transfer all your Xbox 360 game licenses to your Xbox Series X.

Once you've transferred your licenses, you'll be able to access DLC for your Xbox 360 games on your Xbox Series X.

If you are having trouble transferring licenses, you can try the following:

Make sure you are connected to the Internet.
Sign out and sign back in to your Microsoft account on your Xbox Series X.

Restart your Xbox Series X.

It seems to be a little more complicated with the Series s and x now as the account that to be set to home on the console that you'll use the most for other accounts to use some/all of the DLC.

My Series X is set to home on my main account and the other accounts can use any digital games and DLC no problem but on my Series S it's problematic to what DLC can be used since it's not my main accounts home console.

Not really...

Xbox Series X games / upgrades / updates has to be installed onto the Series X internal or expansion card SSD,

You can have Xbox One games on your external hard drive that will get an Series X upgrade but the games will need to be transferred to the Series X and then the Series X upgrade will need to be downloaded onto the Series X SSD,

As an example...

I have Marvel Avengers on my external hard drive that will get the Series X upgrade and I will transfer the game over to the Series X SSD ready to download and update the game to the Series X version when available.
