Legacy System Analysis
Systems nobody who built them still supports, running on decades-old technology you can't afford to lose. We figure out what they do and how to change them safely.
Some systems don't get replaced because they're good. They get kept because replacing them is terrifying. The system has been running for 20 or 30 years, it's load-bearing for the business, and everyone involved in building it retired, moved on, or the vendor that made it doesn't exist anymore.
Stuck on decades-old technology: The platform it runs on is obsolete. The language it's written in barely has developers left who know it. The original hardware it was designed for is long gone, and it's been kept alive through workarounds nobody fully trusts. Every year that passes, the risk of a catastrophic, unrecoverable failure goes up, and the pool of people who could fix it goes down.
Can't procure the documentation: Whatever documentation existed was lost, was never written, or belonged to a vendor who won't return your calls. Support contracts expired years ago. You're operating a business-critical system with no map of how it actually works.
We analyze legacy systems end to end: the application logic, the data it depends on, the integrations bolted onto it over the years, and the operational quirks that only show up under real load. We're not scared of old technology, decades-old languages and platforms are exactly the kind of thing we've spent our careers in.
What We Deliver
A full picture of what the system does and why it was built that way, including the undocumented dependencies that would break something else if you touched them. A migration or modernization path, if that's the goal, planned around what the system actually does rather than what the diagrams say it does. Or, if replacement isn't on the table yet, a stabilization plan that keeps it running safely until it is.
You don't need the original team. You need someone willing to go in and figure it out. We can do it.
