Legacy modernization without the big-bang risk.

How do you modernize legacy applications?

Assess the system, carve the work into phases, then migrate strangler-fig style: the new system is built alongside the old one and takes traffic component by component. A constrained replatform ships in eight to twelve weeks. There is no big-bang cutover, and you can stop at any phase boundary.

What are the 7 R's of modernization?

Retire, retain, rehost, relocate, repurchase, replatform, and refactor (or rearchitect). Most real programmes mix several: retire the dead weight, rehost what runs fine as-is, and save the expensive refactoring for the components that actually constrain the business. The Full Technical Assessment assigns one of the seven to each part of your estate, with reasons you can challenge.

What does legacy modernization cost?

Every engagement begins with a Full Technical Assessment, $25,000 to $50,000 depending on estate size, two to four weeks of senior engineering time, an honest review of your system, and a phased plan with milestone pricing for the work that follows. The assessment is the only fixed-price item; the modernisation itself is priced phase-by-phase against the plan you sign off on, with no surprises.

How long does legacy system modernization take?

There's no honest one-line answer, it depends on what's being modernised. A constrained replatform might be eight to twelve weeks; a full platform consolidation across multiple legacy systems is closer to a year. The Full Technical Assessment exists to give you a real number for your situation, not a marketing average. Phases are milestone-bound, so you can stop, redirect, or extend at any boundary.

Will our system keep running while you modernise it?

Yes. We use strangler-fig migration, the new system is built alongside the existing one, with traffic gradually moved across as components prove themselves. We never sequence a project as “switch over on a Friday and pray.” If there isn't a path to a zero-downtime cutover, we'll tell you in the Full Technical Assessment and rescope.

How do you avoid the big-bang rewrite everyone warns about?

By refusing to do one. Every engagement is broken into discrete phases with their own milestones and acceptance criteria. You can stop at the end of any phase. We've seen too many multi-year rewrites collapse under their own weight; the playbook is to ship something useful every few months and let value compound, rather than betting the business on a single rebuild.

Do you take over the system, or work alongside our team?

Alongside. Knowledge transfer is built into every phase, pair programming, documentation, training. When we leave, your team can maintain and extend everything we've built. We're not interested in becoming the only people who understand your platform; that's a worse position for you than the one you started in.

What's the difference between modernisation and a cloud migration?

Migration moves the workload; modernisation also fixes the architecture that makes the workload hard to run. You can migrate without modernising (lift-and-shift), but you'll often end up paying cloud prices for data-centre architecture. The operating-model gap behind most failed cloud migrations is the same one that turns modernisations into “two years and nothing changed.”
