Is there a way to migrate my application to Render without serving an invalid SSL certificate for a while?
I have my old application served up on
legacyhost.com, CNAME’d to
mydomain.com. Now Render wants me to change that CNAME to
somedomain.onrender.com. When I do that, users will attempt to connect to Render before Render has acquired a valid SSL certificate from Let’s Encrypt.
fly.io has this feature where one can start the ACME challenge while the CNAME still points to the old, working host: Custom Domains and SSL Certificates · Fly Docs
Is it possible to replicate that with render?
