Built by people who migrate these systems.

Sector7

Established in October 1985, Sector7 has performed over 1,500 complex migrations, with more than 40 VX/TOOLS migration products built along the way. LegacyPhoenix puts that experience into a product: the parsers know the languages and the middleware, and the proof is built around running the original application.

Why now

For most of its history Sector7 has done one thing: large, complex migrations, carried out by its own engineers with its own tools. After IBM acquired the server consolidation business in 2003, Sector7 stayed small by choice and kept to that work. In more than 40 years it has never failed in a migration or rehosting project it has undertaken.

AI has changed the field. Sector7 has been building agentic tools and running migrations orchestrated by AI. LegacyPhoenix is the next step: a validated way to refactor. AI repurposes the business logic, AI derives the test cases from the legacy system, and those tests decide whether the new code is right.

IBM's Migration Factory

In 1997 IBM asked Sector7 to provide a world-wide UNIX to UNIX server consolidation practice. That practice became known as IBM's Migration Factory, porting thousands of applications from Sun and HP to IBM Linux and IBM AIX. In 2003 IBM acquired that server consolidation business from Sector7, with its intellectual property and Sector7's two patents. Sector7 was granted a licence to keep using the patents. IBM did not acquire Sector7 or its OpenVMS capability.

Two patents

• US 7,616,583: Method and program product for consolidating computer hardware resources
• US 8,869,124: Method and program product for costing and planning the re-hosting of computer-based applications

Status

LegacyPhoenix is in development. A working prototype converts a sample OpenVMS application to Java and replays a recorded set of transactions with identical results. The pages of this site mark what works today and what is still being built.
