I'm manually duplicating an old WordPress blog (2.7.1), because it can't be exported/imported automatically (a long story). It's a rather small blog, so it's not that big a deal to recreate it manually in version 2.8.
The problem is that I want the old archved posts to be in the same order on the new blog (hopefully with the same old dates) as they used to be on the old blog.
Is there a plugin or other method of modifying the post dates and post order after I duplicate the archived posts by doing new posts? Or do I have to do the edits to the MySQL database directly. If I have to edit the database (never done so before) will MyPHPAdmin allow me to edit successfully? Won't mess up the tables? Naturally, I'll keep database backups.
