Sitewide redirect

Hello,

I just recently moved my site to a new domain and I would like to create a site wide redirect for my old domain since people are still accessing it, here is an example of what I am trying to achieve.

oldsite.com/about > newsite.com/about
oldsite.com/contact > newsite.com/contact

The structure is the same, the only thing that has changes is the domain, how can I achieve this site wide equivalent redirects in the redirection tool?

Thank you so much!
