What's the best approach for moving and redirecting site?

I have a client who wants new website with different URL, and redirect traffic from her old site to the new one. But she only wants to transfer about half of her blog posts.

I can do a simple 301 redirect in .htaccess file for her old site, but I’d assume that will result in bunch of 404 errors if page and post slugs don’t match perfectly. Ideally, I’d like to set up a 301 redirect for all her site, but redirect to the front page of the new site if slugs don’t match. Is this possible to implement fairly simply?

I see that there are number of plugins for rediretion, but does anyone recommend one from the others?

Thanks in advance.
