Website migration - htaccess

Hi guys I am migrating an old site domain to a new domain. Just wondering with htaccess; does it only redirect if the URLs are the same after migration? E.g.

If my old domain is ____.com/contactus and I change it to a new domain ____.com/contactus htaccess works.

BUT if the old domain's URL is ____.com/contactus and I change it to the new domain (which now has a different URL) like ____.com/contact-us or something like that - does that still work?
