Phew! I’ve now migrated 2 blogs (this one and a pretty dead one) to WordPress 2.6.1. Hooray! It was a much bigger job than usual because my run-by-friends-of-a-friend-in-their-spare-time ISP hadn’t upgraded the MySQL database software beyond version 3.23! I had done all the steps in the WordPress upgrade instructions and clicked on the upgrade database link, and then got the error: WordPress 2.6.1 needs MySQL 4.0.0. 
To give them their due, they set up a MySQL 5.0 database for me very quickly. But that was an empty database, so I had to schlep all the data from the old database to the new one, without any nice tools like phpMyAdmin 
Oh, and I couldn’t do it all in one go because I got weird out-of-space messages.
Because I exhibit the weird obsessive laziness of the geek, I had to write some scripts to save time (I will only actually save time if I remember to run them each time I upgrade), and because I’m rusty I had to look up shell scripting and some MySQL. (Yeah, really quick. The documentation was good, but I was v. rusty.)
Anyway, enough rambling. Katy took the children off to this Celtic place today, and they all came back tired but happy. (K and L came back with painted faces too - K’s was excellent.) I haven’t bothered to upload photos yet, but will in the next day or so.
