Well, the site migration is finished, with only a very few minor glitches, for which I am quite grateful. I'm already very impressed with my new host,
Laughing Squid - apparently this is how a real domain host is supposed to work - they actually have a decent control panel interface, actual tools that I can use to administer the database, real reports on traffic and such and well, damn, it’s nice.
Now that I’ve gotten the site migration done, I can finish with the LJ-to-WP history migration. That may take a little while, but at least I’ve got the working tools to do it now.
The DNS propagation still isn’t 100%, but by the morning it should all be there.
