If you just migrated your WordPress blog from one permalink structure to another, and you don’t want to lose Pagerank or traffic that accesses your blog through the old permalinks, this is for you.
Right before the old permalink generates a 404, this simple plugin grabs the slug from the end of the request and checks if there’s a post with this slug living somewhere else on your blog. If so, it will generate a “301 Moved Permanently” error, which automatically forwards your visitor (and Googlebot) to the new location of your post. It’s simple, but effective. No configuration options, just plug and play.

Many older WP sites used categories and/or pages to organize what were essentially subsites without proper access control and other site-specific goodies like themes, widgets, and plugins.
This plugin lets you move that content to another site on your WordPress network with a single click, with seamless redirects.
This is beta software. Back stuff up first. (I shouldn’t have to tell you that, right?)

Move to Subsite

Move posts in a category and/or a page hierarchy to a new subsite, with seamless redirects.
