Ditching Host-gator Hosting for Nixihost

So finally had enough of HostGator and going with Nixihost for hosting.

I only transferred hosting once before and it was a while back.

I got my domain through porkbun. I intend to keep it with them. Besides backing up my database from myPHPAdmin and wordpress site is there anything else I need to do? Will Nixihost tell Hostgator to transfer hosting to them after I buy it or do I need to let HG know?
