Thank you for getting in touch with us.

You can do that easily with .htaccess:

This type of redirect is tricky with Rank Math as it requires knowledge of regex and you have to keep WP and Rank Math always installed on the old domain.

Here is our guide on creating redirects with Rank Math:

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
