An error occurred upgrading from Wordpress 1.5 to 2.5, and so this will take a while. In effect this means I have to wipe my tables (which I have backed up, of course), make a clean new install, and then reinsert all old comments and articles.
Since I have already written about a planned migration of the blog from self-hosting on my university to don't-worry-about-it hosting on wordpress.com, I think I will use this "opportunity" to do it now.
First I need to upload all the images I have used
to my upload space on wordpress.com. Then I will use
some form of edit/replace on the database dump I have,
replacing something like /kopseng/imgs/ with "http://oligofren.files.wordpress.com/2008/04/"
I will keep the images used so far on this (folk.ntnu.no) server, and rather just upload images used in future posts to the Wordpress.com blog. The reason for not uploading all the files is that it seems you can only upload one picture at a time. That takes way too much time, and considering the fact that I probably keep my account (and thus pictures) at ntnu for at least three years, these pictures really won't matter to much by the time I don't have access to them anymore.
I still have to do some find/replace, replacing all relative urls with absolute, so that in stead of /kopseng/imgs/pic1.jpg I get http://folk.ntnu.no/kopseng/imgs/pic1.jpg.
After getting it up and running, I need to export my content to a suitable import format for Wordpress, called WordPress eXtended RSS (WXR) file. I can then just go to setup, choose Administer, Import, Wordpress, "Upload file".
Hopefully, all will be good :)
Hope to see you back in a few hours!
