Enterprise Code Migration

PROJECT OVERVIEW

Automating legacy integration modernization.

Enterprise migration projects traditionally require developers to manually understand legacy workflows, recreate individual components and assemble them into equivalent workflows on a modern platform.

This solution follows a hybrid approach. Rule-based Python logic handles deterministic workflow processing, while LLMs are used for semantic code generation where traditional transformation rules are difficult to maintain.

RULE-BASED

Component Processing

Python-based processing extracts components and reconstructs the logical structure of legacy workflows.

GENERATIVE AI

Code Generation

Prompt engineering and LLMs generate target-platform code for individual migration components.

VALIDATION

Review & Gap Detection

Generated output is reviewed to identify migration gaps and scenarios requiring developer intervention.

MIGRATION PIPELINE

How the migration system works.

The pipeline separates deterministic workflow processing from AI-powered code generation and uses the reconstructed workflow again during final assembly.

01

SOURCE

Legacy Workflow

BizTalk or TIBCO BW6 workflow definitions containing enterprise integration logic and component relationships.

02

RULE-BASED PYTHON

Component Extraction

Parses the legacy definition and identifies individual components, configuration details and workflow relationships.

03

RULE-BASED PYTHON

Logical Workflow Construction

Reconstructs the sequence and relationships between extracted components to create a logical representation of the original workflow.

04

AI INPUT PREPARATION

Prepare Context for Code Generation

Two pieces of information are prepared for the LLM: the extracted component context and the logical workflow that provides structural information.

A

INPUT

Component Context

Component type, properties, source logic and transformation requirements extracted from the legacy workflow.

B

REFERENCE

Logical Workflow

The workflow structure created during the previous stage, used to provide context for correct component generation and later assembly.

CONTEXT PREPARED FOR LLM
05

LLM + PROMPT ENGINEERING

Component Code Generation

Engineered prompts combine component-specific information with the required target-platform rules to generate the corresponding target code.

06

GENERATED COMPONENTS

Target Components

Individual target-platform components generated by the LLM are collected for the final workflow assembly stage.

07

RULE-BASED PYTHON

Workflow Assembly

Generated components are assembled according to the logical workflow created during the extraction stage.

08

VALIDATION

Validate & Review

Reviews the generated output and identifies migration gaps, unsupported patterns and areas requiring manual developer intervention.

09

OUTPUT

Target Platform Workflow

An assembled target-platform workflow with generated components and identified migration gaps available for further review.

ENGINEERING APPROACH

Why a hybrid approach?

The system does not rely entirely on Generative AI. Each part of the migration pipeline uses the technique that is best suited to the problem.

Rule-Based Automation

Used for deterministic operations where predictable behaviour is important.

  • • Component extraction
  • • Workflow reconstruction
  • • Component organization
  • • Workflow assembly

LLM-Based Generation

Used for semantic translation where legacy and target platforms have different implementation patterns.

  • • Component code generation
  • • Prompt engineering
  • • Target-platform transformation
  • • Handling complex transformation logic

MIGRATION APPLICATIONS

Applied across enterprise integration platforms.

MIGRATION 01

BizTalk → Azure Data Factory

Developed a Python-based transformation engine to automate migration of BizTalk workflows into Azure Data Factory implementations.

The solution combined deterministic component extraction and workflow construction with LLM-powered generation of target-platform code.

MIGRATION 02

TIBCO BW6 → MuleSoft

Developed Python and Java-based automation to support migration of TIBCO BusinessWorks workflows into MuleSoft implementations.

The automation combined structured workflow processing with generated target-platform code to reduce repetitive manual development.

ENGINEERING CHALLENGES

Problems solved by the architecture.

CHALLENGE 01

Preserving workflow structure

Individual component migration is not sufficient because relationships and execution order also need to be preserved.

APPROACH

A rule-based Python stage reconstructs the logical workflow and keeps it available for final assembly.

CHALLENGE 02

Platform-specific transformation

Legacy and target integration platforms expose different constructs and implementation patterns.

APPROACH

LLM-based generation translates component logic into target-platform implementations using structured prompts and context.

CHALLENGE 03

Incomplete generated output

Generated code may not fully support every legacy pattern or platform-specific scenario.

APPROACH

A validation and review stage identifies migration gaps and highlights cases requiring developer intervention.

CHALLENGE 04

Correct workflow assembly

Independently generated components must still be placed in the correct overall workflow structure.

APPROACH

Rule-based Python assembly reconstructs the final workflow using the logical workflow created earlier.

IMPACT

Reducing manual effort in enterprise modernization.

The hybrid architecture automated significant portions of repetitive migration work while retaining deterministic control over workflow structure and human review for migration exceptions.
