Overview
A legacy system is software still running a business but built on technology the current team struggles to maintain — an old framework, an unsupported language version, or an architecture no one who built it is still around to explain. Age isn’t the defining factor; difficulty of safe change is.
Why it matters
Legacy systems slow everything down: features take longer, hiring gets harder because fewer developers know the stack, and every change carries more risk of breaking something undocumented. Ignoring the problem doesn’t remove the cost, it just defers it — usually until the system fails at the worst possible moment.
How Dotcode applies it
We modernize legacy systems incrementally where we can, so the business keeps running on the old system while the new one catches up piece by piece.
