Legacy analysis agents
Scan old applications, recover dependency graphs, extract business rules, and turn undocumented behavior into migration specs.
AI agents for legacy code migration
ShiftCodex translates old systems into modern codebases.
Our agents read legacy applications, map the hidden business logic, generate safety tests, and migrate old languages into modern production stacks.

Modernization agents
A migration pipeline that understands code before rewriting it.
Translation agents
Convert COBOL, VB6, Delphi, classic Java, PHP, and other legacy code into modern languages and service patterns.
Test generation
Produce characterization tests, data fixtures, and parity checks so migrated code keeps the old system's business behavior.
Engineer review console
Route risky changes to human reviewers with traceable diffs, source references, confidence scores, and rollback notes.
Migration model
Modernization fails when translation outruns understanding.
ShiftCodex keeps agent work inspectable. Every migration step links back to the source code, recovered intent, generated tests, and human approval trail.
01
Recover how the legacy system behaves.
Build dependency maps, isolate business rules, and identify modules that can move safely first.
Delivery
From legacy inventory to modern code without blind rewrites.
-
Week 1
Codebase inventory
Choose one legacy application, map its modules, and identify the safest modernization path.
-
Week 2
Agent migration pilot
Translate a contained module, generate parity tests, and compare behavior against the original system.
-
Week 3
Reviewed rollout
Move approved code into the target stack with traceable diffs, rollback notes, and engineer ownership.
