Program conversion—One successful paradigm
Charles Lynn, Jean Risley, ROBERT WELLS · 1979 International Workshop on Managing Requirements Knowledge (MARK) · 1979
The continuing rapid development of computer hardware over the years has been both a blessing to the user who sees his computing power increase and cost decrease over time, and a disappointment to those who have found that the cost of converting existing software outweighs the advantages of the new machines. For any proposed change of hardware, there are at least three options whose cost the user must carefully weigh-(1) the option of remaining with older hardware, (2) the option of completely redesigning/rewriting existent software and (3) the option of converting those portions of the existing software which are portable and rewriting the rest.
