How to move an instance of AWS application from us-east-1d to us-east-1b?

I have an example that I accidentally installed on us-east-1d without even realizing it. I have another application that is supposed to connect but expires. I've contacted AWS support and they've explained why, because the connection does not go through the load balancer that only works for us-east-1a and us-east- instances. 1b. Is there an easy way to move my instance of us-east-1d to us-east-1a or us-east-1b?

Thank you.
