Re: IF I UPGRADE TO PRO I PAY ONLY THE DIFFERENCE ?

You can find all the info here @XZHoRo: https://help.ea.com/en/help/ea-play/upgrade-to-ea-play-pro-for-pc/

How do I upgrade?

If you’ve already got an EA Play for PC membership but you’re ready to go Pro:

1. Go to your EA Account Settings.
2. In the navigation panel on the left-hand side, click on EA Play.
3. Next to Membership, click Change.
4. On the new page that opens, click Change Membership.
5. Choose whether you want to upgrade to the monthly or yearly plan for EA Play Pro, then click Confirm Change.

Congratulations! Now you can make the most of your membership with EA Play Pro.

Once your payment goes through for the upgrade, we’ll refund you for the remaining time on your paid EA Play membership. That refund will go back to your original payment method.
