Framework upgrades to .NET 8, Java 21 and React, done in 30 days
Your framework's end-of-life date has passed or sits on the calendar, and every security scan lists the same findings. Engineers with 25+ years in production put you on a supported version in 30 days, proven on your own traffic.
Within 48 hours: a fixed price per phase, the upgrade order and the date your old runtime is gone.
Java 8, .NET Framework 4.x or AngularJS 1.x, patches over, and a scanner report longer every quarter.

The upgrade in 30 days
- 01days 1–3
Scan and plan
Every dependency, deprecated API and removed namespace found across the codebase, with your security findings matched to them. You get the upgrade order and a fixed price.
- 02days 3–15
Upgrade the core
Runtime, build and framework move first: javax to jakarta, System.Web to ASP.NET Core, Struts and EJB to Spring Boot. The platform does the bulk rewrite and engineers review every pull request.
- 03days 10–24
Replace what died
Libraries with no supported version are swapped or rewritten, and AngularJS screens are rebuilt in React one route at a time. The parity harness replays production traffic after each merge.
- 04days 22–30
Ship and retire
The new build takes traffic behind a switch, with the old runtime kept as a fallback until you sign. Then it is removed from every server and image.
Who does what in an upgrade
Finding every deprecated and removed API
Platform
Across all modules and transitive dependencies, including reflection and XML config the compiler never sees.
Bulk code changes
Platform
Namespace moves, API replacements and syntax updates applied across the codebase as reviewable pull requests.
Replacing dead libraries
Engineer
Which library takes over from one that stopped at Java 8 or .NET Framework, or whether a few lines of your own code are safer.
Closing security findings
Both
The platform maps the scanner report to fixes. Engineers verify each finding closes and that nothing new opens.
Behaviour parity
Both
Replay of recorded traffic is automated. Your side signs off which differences are fixes and which would be regressions.
Performance on the new runtime
Engineer
Garbage collector, thread pools and startup tuned on the new runtime and measured under production load before cutover.
An automated codemod handles the easy half of an upgrade. Every change here also passes a senior engineer and the parity harness before production.
Who does your upgrade
Our engineers have been writing production Java, .NET, Python and PHP for more than 25 years, and shipped on the versions you are leaving. They know which Spring XML config stops loading without a word, where .NET 8 serializes a date differently, and how an AngularJS digest cycle hid a race for years. For an upgrade that changes the runtime and keeps every answer, they are the best people you can put on it.
Fixed price per phase, with the retirement date of the old runtime in the contract. A phase is accepted when the parity report is clean, and every commit is yours as it lands.
What engineering leads ask us
Can our team keep shipping features during the upgrade?
Yes. We work on a branch rebased on your main every day, and the platform reapplies the mechanical changes to whatever you merged. Your roadmap keeps moving while the upgrade lands underneath it. Get a quote and the plan shows how merges flow from the first day.
We have almost no tests. How do you prove nothing broke?
The parity harness replays recorded production traffic against the old version and the new one and compares every response, so the paths your users take are covered whether tests exist or not. You get a diff report per phase and sign it before cutover. Get a quote and the harness is in the price.
AngularJS to React sounds like a full rewrite. Is it?
It is a rewrite of the front end, done route by route inside the running app, so users see screens change one at a time and there is no big-bang release. The platform ports templates and controllers to components, and engineers review each one. The whole front end is on React within the 30 days. Include the route count and the price comes back in 48 hours.
Our framework reaches end of life soon. Is there still time?
Yes. The upgrade takes 30 days, so starting this week puts you on a supported version well ahead of the deadline, and your next security audit meets a current runtime. Get a quote today and the date goes into the contract.
Why not have our own team do the upgrade?
They can, and it takes them off the roadmap for as long as it lasts. We bring a platform that makes the mechanical changes across the whole codebase at once, plus engineers who have done this exact upgrade before. Your people stay on features. Get a quote and set it against what your roadmap would lose.
Get off the unsupported runtime
Name the framework, the version and the deadline today. Within 48 hours you have a fixed price and an upgrade order, and in 30 days production runs on a supported runtime with the old one deleted.
Version numbers and a rough repository size are enough to put a price on it.
