In varibale you mentioned to match URI but in class its full URL.

Try below iRule...

     class myRedirects_dg { 
        "/how-it-works https://new.domain/new-base-dir/pages/about"
        "/contact https://new.domain/new-base-dir/pages/help"
        }

    when HTTP_REQUEST {
       set destLoc [findclass [string tolower [HTTP::uri]] myRedirects_dg]
       if { $destLoc ne "" }{
       HTTP::redirect [getfield $destLoc " " 2][HTTP::uri] Connection Close
          unset destLoc
           } else {
               HTTP::redirect https://new.domain/new-base-dir[HTTP::uri] 
        }
    }

Still no luck. I was using URI and the contains option to be more greedy about the search. I can use the elements exactly from the Data Group if that's easier.
