Don't think it lets you get at the old CC info now...have to transfer to the new payment methods, which doesn't have a direct CC payment option for the non-JP regions (not yet, at least...something supposed to be coming in the fall). So, you'll have to transfer and setup either a Crysta account or go with Click&Buy. I set up the crysta account first, and it transferred to that method without a hitch (even though I had a 0 Crysta balance).

After you get things transferred over, you have options to re-activate ID's and such within the new SEAM system--but I think there where some issues with reactivation they are still trying to fix.
