How to keep the "Referer" between domain redirects done with Cloudflare?

I did a domain migration and redirected the old domain to the new address with page rules. How can I keep the “Referer” in logs between the domain redirects?

Looking at the Cloudflare Analytics for the new domain the logs that are redirects from the old domain have no “Referer” and are shown as Direct traffic. I want to see which logs are specifically coming from the old address. Is it possible?
