I agree that making the change is preferable to reimplementing. Just saying you can’t assume that an old and battle tested codebase is an ops problem rather than a dev problem. There’s going to be some point where you’ll be glad to have original specs and docs and source code on hand (along with a good COBOL dev) so you don’t have to decompile and reverse engineer the damn thing. (Which IIRC had to be done for a relatively large percentage of COBOL-era systems updated for Y2K.)
