How do I move static IP address from one ISP to another

Unless the ISPs share netblocks (very unlikely), this is not a realistic outcome.

If you're looking to keep the static IP for DNS reasons, you should instead lower your TTLs and keep both ISPs (and by extension, IP addresses) until you can gracefully migrate.

Unless you own the IP address block it's in, and it's in Provider Independent (PI) Space, then you might be able to switch transit providers, and announce your routes over your new BGP sessions with your new ISP, then it might be possible.

Given the lack of networking knowledge show in the OP's question, these assumptions seem unlikely.
