Changed credit cards so have 2 statements with 2 different accounts the same dates

We recently changed the type of credit cards we have.  Still same company but we have different account numbers than before.  I have a statement for one period for the old account and one for the same period with the new account.  Since the statement start dates are automatic from the last month end date, would it be best to create a new account number in Sage 50 for the new cards?
