301 Redirecta for old pages in Runway

Hey guys. I am about to launch a new site for a client. It is the first Runway site I have done that will be going live (done lots of ‘normal’ Perch sites before). But I have a question over 301 redirects for all the old pages (there are quite a few).

Traditionally I would add these into a .htaccess file for example;
Redirect 301 /services/ /products/

But with Runway should I still maintain this approach? or should I be adding each old URL as a route on that particular page? But then does this cause an issue with duplicate content and how do I avoid this? Canonical META tag perhaps?

Any advise or suggestions - welcome.

Thanks.
