Fix the software that's holding the business hostage.
Almost every mid-market firm has one system everyone hates and nobody will touch — too risky to replace, too painful to live with. We modernize legacy software through a structured approach: stabilize first, refactor second, replace last. No big-bang rewrites.

Why legacy systems are a slow crisis.
The system runs on Windows Server 2008.
Out of support since 2020. Microsoft won't issue security patches. Auditor flagged it. Nobody knows how to upgrade.
One person maintains it. They're retiring.
Single-point-of-knowledge. After they leave, nobody can fix it.
Last attempt to replace it was a 2-year failed project.
Sunk cost on a rewrite that never shipped. Team morale is wrecked. Leadership is gun-shy.
Vendor went out of business.
Software still runs. No more updates. No support. Time bomb.
How we modernize.
- 01
Current-state assessment
Map the system. Code, infrastructure, dependencies, business value, risk. Documented.
- 02
Stabilize first
Before any modernization, make the system safe. Backup it works. Disaster recovery plan. Security patches where possible.
- 03
Strangler-fig approach
Replace piece by piece. Each piece shippable on its own. New code lives next to old; old retires gradually.
- 04
Documentation as we go
Even before code changes, document. Knowledge captured. Single-point-of-knowledge risk reduced from day one.
- 05
Phased delivery
Quarterly milestones with shipped value. Nobody waits 18 months for a working result.
- 06
Knowledge transfer
Your team learns the new system as it's built. No black box. No another single point of knowledge.
Three modernization strategies.
We rarely recommend big-bang rewrites. The middle paths usually win.
| Big-bang rewrite | Strangler fig | Refactor in place | |
|---|---|---|---|
| Project length | 12–36 months | 6–18 months phased | Continuous |
| Risk | High — all or nothing | Low — incremental | Medium |
| Value delivery | Big-bang | Continuous | Continuous |
| Business disruption | High at cutover | Low | Minimal |
| Cost certainty | Poor | Better | Good |
| When to use | Rarely — too risky | Most cases | When stack still has life |
A typical modernization arc.
- Month 1
Stabilize
Backups verified. DR tested. Critical patches. Knowledge documented. Risk reduced before any change.
- Months 2–3
Assess + design
Map the system. Identify modernization candidates. Sequence priorities. Architecture sketched for the new world.
- Months 4–6
First strangler piece
Pick a self-contained module. Build replacement. Run alongside. Cut over when proven.
- Months 7–18
Roll forward
Phase after phase. Each piece ships independently. Legacy shrinks. New grows.
- Eventually
Legacy decommission
Old system retired piece by piece. Final cutover is small because most has already moved.
What clients see.
Of our modernization engagements. We don't recommend them.
First valuable modernization delivered within 90 days.
Before any code change. We don't accelerate broken systems.
Across modernized pieces, post-deployment first 30 days.
“Our case management system was a 14-year-old VB6 monolith. Two prior agencies tried rewrites and failed. Senator stabilized it first, then replaced it piece by piece over 11 months. We never had a no-work day. Couldn't be happier.”
Who needs this.
- Firms with mission-critical systems on out-of-support platforms.
- Anyone whose legacy system is maintained by 1–2 people about to retire.
- Acquired firms with unmaintained inherited systems.
- Anyone who's tried (and failed) a previous big-bang rewrite.
Q01What if we have to retire the legacy system fast?
What if we have to retire the legacy system fast?
Sometimes — emergency cases (vendor bankruptcy, security exposure) we move quickly. Even then, the strangler approach usually beats big-bang.
Q02Can we keep our existing team?
Can we keep our existing team?
Yes — and we want you to. They know the business. We bring modernization expertise. We pair.
Q03What languages do you work in?
What languages do you work in?
We've modernized Java, C#, VB6, Delphi, COBOL, Perl, classic ASP, ColdFusion. Modernization is more about discipline than language.
Q04How do we know it's working?
How do we know it's working?
Every quarter, value shipped to production. Working software. Trail of decisions. No 18-month mysteries.
