What I meant by the data storage or structure changing is that they were moving to a new platform or completely changing the backend. That way the legacy front-end no longer works with the new platform. If they build code to keep the data in sync across both, they could run in parallel.

Don't know man; some financial institutions have such Antiquated systems and software (think Honeywell mainframes running ANSI COBOL) that there's no telling what they migrated from or to. I've seen some real odd systems over the years, especially during Y2K when everyone was moving off large IBM or Honeywell platforms to client server or distributed middleware systems.

I know, currently working with mostly industrial clients and a lot of them are still using mainframes for their business critical systems. I haven't worked with Banks in a while but the account and transaction data is usually on older systems. Then all the front-end, fraud, customer info, etc is what gets updated.
