Redirect all posts from / to /blog/

First, thanks for the awesome plugin. Sorry if this has been answered elsewhere. We would like to change the permalink structure from %postname% to /blog/%postname% and redirect any requests to posts at the old URL to the new structure.

My guess is that I need to export the %/postname/% of all existing posts and use the import function of the plugin.

But before I do that I wanted to see if there was a more automatic way to achieve what we’re after.

Thanks again!
Colin
