Performances can be taken off-sale:
a) on the web so they are only accessible via Box Office
b) on both Box Office and on the Web so they are inactive and not on sale anymore. If there are existing sales that need to be shifted on the performance you want to make inactive, make the performance box office only at first so you can still see them and see here for more info on moving bookings and transfers:
