I've got a domain, example.com which has a lot of links/web addresses indexed so I wish to point all web addresses after the / for an aged.example.com. Basically something similar to this:

RewriteEngine On
RewriteRule (.*) http://archived.example.com/$1

However, I wish to leave example.com alone (meaning I'm not going example.com to visit aged.example.com, just the web addresses following the /)

How do i accomplish this? I looked through other similar questions about here, but none of them appear to achieve the same issue.
