Do I need redirects for a .asp to a .htm?

[EcommerceSite]

We move to a new site and some of the pages were widgets.com/test.asp, do I need to redirect that to widgets.com/test.htm? It is the same url just the difference between .asp and .htm

Yes, you should 301 redirect .asp pages to .htm even if they have the same page name.

Yes, you do need to redirect. They are actually different URLs. It's like you moved from 123 Fifth Avenue to 123 Fifth Street.
