WooCommerce update performed on 2.2.2

Hi, I have the WooCommerce update performed on 2.2.2 with. Now I have some php-files, which are declared as obsolete. Message is: Your theme contains legacy versions of WooCommerce design templates e.g. .: my-address.php Version 2.0.0 is outdated. The main version is 2.2.0 my-orders.php Version 2.1.0 is outdated. The main version is 2.2.0 view-order.php version 2.0.15 is outdated. The main version is 2.2.0 and further such messages. How can I deal with this? Are there files in a single download? If yes -> can I override the “easy” via ftp?
