As others have mentioned this is an extremely odd thing to expect to work....

I'll give an example. I worked for a FTSE 100 company using a very old Product Lifecycle Management system (model manager - based actually on pre-DOS technology)....we had to upgrade it to a new fancy one.

Therefore we had to migrate all data relating to the company, and group companies engineering designs...everything to do with 2D drawings, 3D designs...any important connections etc....all electrical designs....excel sheets related to these containing lists of PCBs and their component parts in Bills Of Materials etc...There is absolutely no way in hell I would trust AI with almost any of that, to get it right....or even to attempt a load without almost immediately erroring.

Totally agree. We wouldn’t trust AI to run that kind of migration either... And we don’t.

But here’s what we do use AI for: • Mapping legacy schemas • Spotting patterns • Generating boilerplate ETL code fast

Then humans step in: • Validate every mapping • Write custom logic for edge cases • Test everything... every field, every BOM, every relationship • Migrate with deterministic, human-reviewed code
