Changing permalinks on a live blog

Yes – except where you’ve manually created a link in your own post or page that points to an internal page within your blog.

In other words, all your past posts and pages will get new url permalinks. Any actual links that you created within a post/page would need changing. You probably won’t have many of those, so it should all be good.

Don’t forget about “other” websites that may have linked to you. Those links will be broken, so you may want to notify those web masters to update their links.
