Question 1

How long does a legacy modernization project take?

Accepted Answer

It depends heavily on codebase size and risk tolerance. A focused migration of one service or module takes 6–12 weeks. A full platform re-architecture for a large product typically runs 6–18 months in phased stages. We always start with an audit (1–2 weeks) that gives you a realistic timeline before any commitment to full scope.

Question 2

Can you modernize our system without taking it offline?

Accepted Answer

Yes — this is a core constraint we design around. We use parallel build, strangler fig, and incremental migration patterns so the existing system stays live throughout. Users experience no downtime. Traffic is migrated in slices with rollback capability at each stage.

Question 3

What if we don't have documentation or tests for the existing system?

Accepted Answer

This is very common. Part of our audit phase is reverse-engineering the system behavior — reading the code, running it, and mapping what it actually does versus what it was supposed to do. We write documentation and tests as we go, so the new system is better-documented than the old one was.

Question 4

Do you work with in-house teams or replace them?

Accepted Answer

Both models work. We often embed alongside an existing engineering team — taking ownership of the migration work while your team continues shipping product features. We can also lead the full engagement if you don't have internal capacity. Either way, knowledge transfer to your team is built into the engagement from the start.

Question 5

How is legacy modernization priced?

Accepted Answer

Most engagements start with a paid technical audit (1–2 weeks, fixed price) that produces a scoped modernization roadmap. From there, we can work fixed-scope per phase or on a time-and-materials basis. Contact us to scope the audit for your system.
