// for businesses on aging custom systems

The system runs the business.
One person runs the system.

An MS Access app, a FoxPro database, a custom ERP nobody dares touch — built years ago, undocumented, and tied to one developer. A rewrite feels too risky. dForge lets you modernize one workflow at a time, on real infrastructure, without a big-bang cutover.

Is your business at risk?

If you recognize a few of these, the system is carrying more risk than the business realizes.

A single developer (or none) keeps a critical system alive.
It's 10+ years old, undocumented, and "don't touch it or it breaks."
A trigger just changed — that person is leaving, an audit, an acquisition.
You've priced a rewrite and it's too big, too risky, all at once.
Two or more? It's worth a conversation before the trigger forces one.Talk to us about a migration
// how dForge fits

Modernize without the big bang.

Start from your existing schema, move one workflow at a time, and end up on infrastructure anyone can read and support.

01

Map your schema into a module

Hand over your existing SQL, DBML, or even the legacy screens. We model your entities, fields, and relationships into a real dForge module — AI-assisted and reviewed with you, not a black box.

  • Bring what you have — SQL, DBML, or the legacy screens themselves.
  • We map entities, fields, and relationships into readable metadata.
  • You get a real module to review and refine — not a black box.

02

Migrate one workflow at a time

Move a single process first, prove it in production, then expand. dForge runs alongside the legacy system during the transition — no risky cutover.

  • Move one process to production and prove it works.
  • Runs alongside the legacy system during the transition.
  • Expand workflow by workflow — never a big-bang cutover.

Real, documented, supported

Postgres under the hood, metadata you can read and review, role-based security built in. The bus-factor problem goes away.

  • Standard PostgreSQL — inspectable, backed up, portable.
  • Metadata you can read and review — not code only one person understands.
  • Role-based security and audit, built in.

// how a migration works

A plan before a single line moves.

No surprise rewrite. We map the system first, agree on scope, then migrate in phases you can stop or adjust at any point.

STEP 01

Discovery call

A short call to map the system, the stack, who maintains it, and what changed to make this urgent now. No demo, no pitch.

STEP 02

Migration assessment

A fixed-scope audit of your data model and workflows that ends in a concrete migration plan — so you decide with facts, not a guess.

STEP 03

Migrate in phases

One workflow to production first, proven, then expand — on documented, supported infrastructure, hosted by us or on your own servers.
