Thought Machine and AWS launch AI solution for banking migrations

Thought Machine and Amazon Web Services (AWS) have launched an AI-powered solution designed to accelerate the migration of legacy core banking systems. The partnership combines AWS Transform’s mainframe reverse engineering capabilities with Thought Machine’s Vault Forge AI tooling suite.

The solution aims to modernize banking infrastructure by converting millions of lines of legacy mainframe code, such as COBOL, into tested financial products within a live sandbox environment. By extracting business intent rather than performing line-by-line code translation, the process can compress multi-year modernization programs into a matter of days.

Unlike traditional legacy cores that hardcode financial products into database infrastructure, Thought Machine’s Vault platform defines products as code using Python. This decoupling allows AI agents to bypass database complexities and translate legacy rules directly into high-level code. The automated pipeline operates within a bank’s secure AWS environment to replicate and migrate product logic through several integrated stages.
