I am about to attempt to import content from The Married Guy Cook to here. If it works, I’ll tweak from there, deleting some of the posts and continuing to set the new site up. If it fails, I’ll remove it all and restore from backup to get to where I was before this post.
Looks like success! I’ve deleted some posts that were meaningless or self-referential to the old blog. All that remains after any more of that is to finish making sure internal links in posts point internally to FGC instead of MGC. Then any other tweaking that would have happened anyway, like category changes, blogroll, etc.
