Retiring developers and undocumented systems create risk that grows every year. Our Legacy System Characterization methodology captures the full intelligence of your ERP — every rule, every dependency, every behavior — so your organization owns that knowledge and controls what happens next.

What Legacy System Characterization Does

Produces a complete functional specification of your ERP and legacy systems

Validates actual system behavior through exhaustive testing

Creates a full code and process map of every function, dependency, and integration point

Eliminates single-point-of-failure dependency on individual developer knowledge

Delivers a clear, documented path to modernization, migration, or continued operation

How it Works
Our Legacy System Characterization follows the SalesE Legacy Intelligence Framework – a four-phase methodology built on a single principle: you cannot safely change a system you don’t fully understand.
1
Characterize
Documents every input, output, business rule, and calculation in your static system
2
Validate
Tests live system behavior to surface undocumented logic and edge cases
3
Map
Produces a complete code map of every process, dependency, and data flow
4
Transition
Defines your path forward: modernize, migrate, convert, or operate with a less specialized team

What It Protects

Captures developer knowledge in system documentation

Closes compliance and audit gaps from undocumented systems

Prevents costly modernization failures caused by incomplete system understanding

Gives your team the access to data and efficiency required for world class operations

Key Benefits

Complete system documentation
your entire organization can use

A validated test library
that proves the system operation

Reduced risk
at every stage of modernization or migration

Control
over your technology roadmap
Knowledge Is the Asset
Your legacy system contains decades of business logic your organization depends on. Legacy System Characterization moves that logic out of aging code and into documentation that gives your team full control, no matter what comes next.
