Method and system for legacy code transformation

A system for facilitating legacy code transformation, the system comprising:

• a processing circuitry;
• and
• a memory communicatively coupled to the processing circuitry, wherein the memory stores processor instructions, which when executed by the processing circuitry, cause the processing circuitry to:
• receive legacy code data and at least one natural language document from one or more data sources;
• generate a first natural language output based on the legacy code data through a first Large Language Model (LLM), and a second natural language output based on the at least one natural language document through a second LLM, wherein the first natural language output comprises domain context or code explanation corresponding to the legacy code data, and wherein the second natural language output comprises extracted knowledge from the at least one natural language document;
• fine-tune at least one of the first LLM or the second LLM based on the first natural language output and the second natural language output, through a third LLM;
• and
• generate a natural language specification document corresponding to the legacy code data based on the first natural language output and the second natural language output through the third LLM.
