We have the same issue as well. If someone from the Apple team can check it, here is our requestReferenceId 3ed709ef-569d-4908-a6fd-6daf9fff092a

The 5000000 error code is a generic server-side error on Apple's end, so it's not something wrong with your request payload per se. A few things worth checking: make sure your sandbox account and the subscription you're migrating are both in a clean state (not expired or in billing retry), double-check that the generic product ID is properly configured and approved in App Store Connect for ACA, and confirm the storefront matches the sandbox account's region. If everything looks right and you're still hitting it, I'd recommend filing a Feedback Assistant ticket with your requestReferenceId so Apple engineering can trace the actual server-side failure.
