Domain Transfer to Cloudflare with existing DNS management in a Cloudflare Tenant

Hello, I have the following question. We need to move a domain from another registrar to Cloudflare, but the DNS of this domain is already managed by another Cloudflare tenant. After the move, the DNS should be managed by our Cloudflare tenant. What is the procedure for a smooth domain transfer in this case?

Greetings and thanks, Christian
