New Domain& Website Created Outside of Homestead

I have a new website created outside of Homestead that is hosted on WIX. I purchased two new domain names as well www.shilohwilmington.com, www.shilohwilmington.org. My current domain name on Homestead is www.shilohwilm.org  what ate the steps to point my existing domain name www.shilohwilm.org to the new website (www.shilohwilmington.org )hosted outside of Homestead.  Do I perform a DNS transfer to WIX or update the DNS records on Homestead.  We are retiring the current website and hosting on Homestead?  Also will this transfer affect our google workspace email configuration?
