01
Understand
Map the application, its interfaces and the rules behind the selected workflow.
- Reviewable output
- A system map, referenced rule record, open questions and migration options.
Application modernization
Change the software.
Preserve the business rules.
Legacy applications often contain essential knowledge that is missing from the documentation. AID helps make that knowledge visible, test the behavior that matters and modernize the system in controlled increments.

01 / The challenge
Before a rewrite,
establish what must survive.
An unsupported runtime may trigger the project. The harder questions sit inside it: pricing rules, exceptions, dependencies and the reports or interfaces that other teams depend on.
Recover system knowledge
Read the code, follow the data and document business rules with references that an engineer can inspect. Confirm uncertain behavior with the process owner.
Protect essential behavior
Create tests around representative transactions, calculations and exceptions. Separate intended changes from regressions.
Plan a manageable release
Choose a bounded part of the system, identify its dependencies and define how it can be deployed, monitored and reversed.
Claude’s role
Accelerate the analysis.
Keep engineering judgment.
Claude can assist with reading code, drafting documentation, proposing changes and creating tests. AID engineers check that work against the application and its requirements.
The modernization plan accounts for the existing architecture and available tooling. A standard upgrade may need less intervention than a system with undocumented rules or custom integrations.
02 / A bounded first release
Make the migration
reviewable.
The first increment establishes a repeatable way to understand, change and verify the application. Its scope is determined after access and dependencies are reviewed.
02
Compare
Run agreed cases against the existing and changed implementation. Examine differences in outputs, data handling and error behavior.
- Reviewable output
- A test suite, comparison report and decisions on intended differences.
03
Release
Complete the release controls, verify integration behavior and transfer the implementation to the operational owner.
- Reviewable output
- Release and rollback instructions, operating guidance and the next increment’s scope.
Before the first discussion
Bring enough context
to scope the work.
A short description of the application and the reason for change is sufficient to begin. Sensitive source code or records do not need to be sent through the contact form.
- The application’s role and critical users.
- Known languages, runtimes and integrations.
- Available documentation and test coverage.
- The business owner and the required decision.
Start a conversation
Start with one application or workflow.
AID can help establish what needs to change, what must be preserved and what evidence will support the first release.
