I have a website about gaming, and I am looking forward to shifting it to Fly. The website is on the website. My website is omggamer.com, and currently, I want to test Fly.io with the subdomain so that I can check the performance. There are some tools that we created that are on different subdomains that will also get shifted to fly if everything goes well. So, how can I do that?
PS: Currently website is with digitalocean and runcloud.
