It depends on how much compiler, operating system, and hardware
specific code you have.

Are you also switching operating systems and hardware? Are you willing
to buy a support contract (probably $10K or more, depending) from ACT?
They can be very helpful.

You should contact ACT, the company that sells support for GNAT. They
offer a free evaluation service; they may be willing to help you port
the application as part of that service. See, or
