If you're trying to get rid of the old one, you'll need to make a new Apple ID or simply not use Game Center when using Hay Day. However, you'll need the old Apple ID to get the old one back. If you only saved it through Game Center, there is virtually no other way to get access to that farm except through Game Center.

And just FYI, I'm simply another fan of Hay Day. This is a fan-run wiki.
