Question 1

Will modernizing my system cause downtime?

Accepted Answer

We mitigate this by using the 'Strangler Fig' pattern. We build the new system alongside the old one, gradually routing traffic to the new microservices piece by piece. This ensures virtually zero downtime during the transition.

Question 2

Should we rewrite the software from scratch or update the existing code?

Accepted Answer

It depends on the state of the codebase. If the business logic is sound but the tech is old, we might wrap it in APIs and migrate it to the cloud. If the code is unmaintainable 'spaghetti', a phased rewrite is usually the most cost-effective long-term solution.

Question 3

How do you decide what to modernize first?

Accepted Answer

We start with a discovery audit that maps which modules cost the most to maintain, carry the highest security risk, or block new revenue. Modernization then follows business value, tackling the painful, high-impact areas first rather than rewriting stable code that works fine.

Question 4

What does a modernization project typically cost?

Accepted Answer

Because we modernize incrementally, you fund it in stages rather than one giant budget. A focused discovery phase produces a costed roadmap, so you can approve work module by module and stop or reprioritize at any point as business needs change.

Question 5

Will the modernized system keep working with our other software?

Accepted Answer

Yes, preserving integrations is a core requirement, not an afterthought. We map every connection to databases, payment systems, and partner APIs up front and wrap or rebuild them so dependent tools keep functioning throughout the transition.

Question 6

Do we keep ownership of the modernized code?

Accepted Answer

You own all source code, documentation, and infrastructure we produce. A key goal of modernization is removing vendor lock-in and undocumented black boxes, so we leave you with clean, well-documented code your own team can maintain.

Question 7

What do you need from us during the project?

Accepted Answer

We need access to the existing codebase, knowledgeable staff who understand current business rules, and any documentation that exists. The biggest accelerator is time with the people who know why the system behaves as it does, since legacy logic is rarely written down.

Question 8

How do you protect against introducing bugs while changing old code?

Accepted Answer

We add automated tests around the existing behavior before changing it, a practice called characterization testing, so any regression is caught immediately. Combined with the strangler-fig pattern of replacing pieces gradually, this keeps the live system stable throughout.
