boxed OneBox update - paid:
If your contract regulates free updates, you can update at any time upon an individual request to technical support (paid) or write a task on the "Update OneBox" forum (free and public).
If your contract does NOT regulate free updates, the procedure is the same, but you will be billed accordingly for the update.
