Legacy System Modernization built for Aerospace & Defense companies
What is Legacy System Modernization?
We modernize legacy systems without breaking the business processes that depend on them. For Aerospace & Defense companies, this means navigating ITAR (US), DO-178C software certification while shipping fast.
Who needs Legacy System Modernization for Aerospace & Defense?
- Stringent security and clearance requirements
- Long procurement and certification cycles
- Legacy system integration complexity
- Legacy systems too fragile for anyone to touch
- Key knowledge locked in one retiring engineer's head

Most Legacy System Modernization engagements take 12-24 weeks depending on system size, depending on scope and how clear the requirements are upfront. We'll give you a firm timeline estimate after a short discovery call, not a generic range.
Legacy System Modernization projects with us typically range from $40,000 - $250,000, scaled to the complexity of your requirements. We provide a detailed, itemized estimate before any work begins so there are no surprises mid-project.
For legacy system modernization, we typically work with Java, .NET, PHP, Node.js, chosen based on your specific scalability and integration requirements. We're not tied to a single stack and will recommend the right tools for your situation rather than our default.
A typical legacy system modernization engagement includes legacy codebase audit and risk assessment, along with the other deliverables outlined in our proposal, such as documentation and a post-launch support window. The exact scope is tailored to your project during discovery.
Most clients come to us for legacy system modernization because of legacy systems too fragile for anyone to touch, among other related challenges. We start every engagement by mapping your specific pain points before writing a single line of code.
We've delivered multiple aerospace & defense projects addressing challenges like stringent security and clearance requirements. We supported an aerospace supplier in modernizing its parts traceability system while maintaining ITAR compliance.
For aerospace & defense clients, we pay close attention to ITAR (US), DO-178C software certification, building these requirements into the architecture from day one rather than retrofitting them later. We'll confirm which specific regulations apply to your business during discovery.
The most common challenges we solve for aerospace & defense clients include stringent security and clearance requirements and long procurement and certification cycles. We tailor our discovery process to surface the specific version of these problems your business faces.
