We're on CiviCRM 4.6.19, Drupal 7.50 and using Authorize.net for payment processing.
When a credit/debit card number, card billing address, or card expiration date has changed, should simply updating the subscription with the new card info in Authorize for an ongoing monthly sustainer continue the processing uninterrupted, on the same date?
UPDATE for clarification - The monthly/recurring amount will remain the same. The goal is to resume the same monthly/recurring contribution in the same amount by fixing an error with processing by updating the "subscription" in Authorize with the new card number, billing address and/or expiration date.
