If the only function of the "old" server is to capture a request and issue a redirect based on the capture, then I can't imagine why it would matter what platform the server is on. It's not even serving up existing content, let alone producing new content.
When shopping for hosting, make sure they support page-for-page redirects. Super-cheap hosting might not; that's how they get to be super-cheap.
