[Verse 1] Forty-year-old COBOL whispers through the port Mainframes hum their ancient digital court Your shiny API speaks REST and JSON clean But legacy customs won't parse what you mean Middleware becomes the diplomatic bridge Screen scraping data from the registry's ridge [Chorus] Wrap and adapt, don't rebuild from scratch Map the old protocols, find the data match Queue the requests when the mainframe sleeps Batch by night what real-time never keeps Transform and tunnel through the compliance maze Legacy integration's puzzle-solving phase [Verse 2] Court dockets locked in SOAP from two thousand three Your GraphQL queries hit walls you can't see File transfer protocol, scheduled at dawn CSV exports when the courthouse has gone Error codes cryptic from Fortran's domain Decode the mysteries or integration's pain [Chorus] Wrap and adapt, don't rebuild from scratch Map the old protocols, find the data match Queue the requests when the mainframe sleeps Batch by night what real-time never keeps Transform and tunnel through the compliance maze Legacy integration's puzzle-solving phase [Bridge] Circuit breakers guard against the timeout storm Retry logic keeps connections warm Cache the lookups that move like molasses Validate twice when the old schema passes Version carefully, rollback prepared Technical debt must be properly shared [Verse 3] Government databases speak in fixed-width fields Character encoding that rarely yields EDI transactions in standardized rows X12 formats that nobody knows Terminal emulation masks modern calls While regulators guard their firewall walls [Chorus] Wrap and adapt, don't rebuild from scratch Map the old protocols, find the data match Queue the requests when the mainframe sleeps Batch by night what real-time never keeps Transform and tunnel through the compliance maze Legacy integration's puzzle-solving phase [Outro] Patient translation builds the lasting link Between tomorrow's code and yesterday's ink Respect the heritage, bridge what remains Modern and legacy share the same chains
