nginx, rack-rewrite and refraction are possible solutions for my migration. It's a simple 1-to-1 mapping from old URLs to a new domain from the old one, e.g. http://old.com/posts/id to http://new.com/posts/id, so hopefully not too hairy. Does anyone have any good/bad experiences with these different approaches or have any comments on the pros/cons of each?
Gratefully,
Kimball
