Dear Customer,
Thank you for contacting the Square Enix Support Centre.
First of all, we would like to apologise for the delay in response, which is due to the high number of Final Fantasy XIV enquiries we receive at the moment.
You will be able to play your Final Fantasy XI account and your Final Fantasy XIV account at the same time, even if they are linked to the same Square Enix ID and the games are on different consoles.
Kind regards,
Square Enix Europe Support Centre
Thank you again for contacting us and for your interest in Square Enix products!
More help and information are available at the Square Enix Support Centre website.
