I have an old WordPress blog that, at its height, got a good bit of attention. I haven't written it in about a year, and I want to start a new blog, but not before this one has been given the send-off it deserves. Too many people link to it and use it for me to just let it disappear. By the same token, I don't want to keep using the resources of an active site.
What are the best practices for shutting down a WordPress blog? I'm running an old version (2.3.3), but I can upgrade if that's what it takes. I'd like to be able to:
(1) At the very least, shut off comments for everything.
(2) It would be nice if I could generate static HTML pages, so that the archives don't put any strain on a database.
Do any tools exist to do this kind of thing?
