The permalink structure on my old blog (now on the subdomain) was /yyyy/mm/dd/name and the permalink structure on the new blog
(on main domain) is /name.
I'm now wondering what the best way to maintain incoming links is?
Should I have a 404 on http://domain.com that looks for the same file on http://sub.domain.com? (i.e. http://domain.com/permalink 404s, so check to see if http://sub.domain.com/permalink exists, and if so, redirect.)
Should I have a mod_rewrite rule that forwards all http://domain.com/yyyy/mm/dd requests to the corresponding location on the subdomain?
What are the pros and cons of doing these? Is there a much, much easier way of doing this?
