We recently moved a site from an old legacy blog app to WordPress. The old system didn't use post slugs which was fine as we were using ?p= for permalinks. Now that we want to move to cleaner permalinks like /%year%/%month%/%title%, we need to go back and add post slugs to a few hundred posts.
I couldn't find a WP plugin which will do this. We could potentially write a PHP script to do this for us but was wondering if there was something already available?
Also, if we go down the custom route, one question. If a post from 1-1-06 has a title of "my blog post" and a post from 8-1-06 has the same post title, I assume WP will be able to know the difference based on the month/year? Also if there are 2 posts in the same month with the same title, is it customary to just add a number at the end?
Thanks in advance.
