Unless the rules were changed recently by DB, I think all long distance tickets are fully reimbursable until the day prior to departure (on the day of departure a 15 EUR cancellation fee is charged). So it would be possible just to cancel the old ticket and get a new one but, of course, that might be more expensive.
