Thanks, Ryo-ohki. Yeah, the One-Click thing makes it so simple you can't see what the heck is going on... I just nuked that install and will go ahead with the method of creating a sub-domain, MySQL database, and manual install of Drupal.
Good advice on the migration. Drupal is very much overkill, but I want to get up to speed on it and will play around with it on the staging site. (Glutton for punishment, I guess.)
I don't care that much about the old blog content. Even so, WP is a much easier tool to work with. I've been using it on the blog for many years. In the end, I may use WP for the new site, too. It will be a relatively simple site.
Thanks again for taking the time to answer.
