I am planning on Migrating our main Domain from another DNS tool to Cloudflare. But being the main domain we have a very complex setup of subdomains pointing to a CNAME Setup in a vendor owned Cloudflare among other things. My question would be how to migrate the main domain and all the subdomains with CNAME Setup with the least downtime/disruption possible. Do I:
- Migrate the Main Org to Cloudflare and then create the subdomains in a Full Setup from vendor Cloudflare Accout to our Cloudflare Account. Or
- Migrate the Subdomain CNAME Setup from the Vendor Account to our Account. Then on a later date migrate the main domain then convert the subdomain from CNAME Setup to Full Setup.
Any suggestion or insight is appreciated. Thanks!
