[Plugin: WordPress SEO by Yoast] With category base stripped, old month/name not redirecting

Hi Yoast,

I have the category base stripped using your plugin, (and if it matters, in my General WP settings, the Permalink setting is postname).

Existing links (both internal and external) that used the month/name permalink are not redirecting to their respective posts/pages. Should they redirect automatically, or do I need to redirect them manually from

http://www.domain.com/2011/12/19/postname/

to

http://www.domain.com/postname/.

If I need to do it manually, I know how, I just want to make sure I didn’t miss something along the way.

Thanks so much for the best SEO plugin.

Angie
