Upgrade WordPress 3.1 to 1.5 done

W ith WP 1.3 Can I was quite happy, has indeed worked well, but the new plug-ins are all written for 1.5. And because I wanted to install, especially the new plug-Side Blog, I had no choice. Since I've modified a lot of files, for me was the way to go:
First WP 1.5 on the new path with a new database table, 2nd All modifications to make and test; 3 Then enter in wp-config-original database information; 4 Rename Path, 5th Upgrade file to start; 6 completed. "Actually," came the matter (except for a few little things to be done) well off the roll. I have this inauthentic "Blog Roll - make - to - large - Categories - headings" bug, of course, two hours sitting. If you also have this prob should (appears when converted themes): \ wp-include, where links.php, line 504, delete the two H2 tags. Man, man, man ...
In any case, the work has paid off - but the dashboard is great, great new plug-ins have been written in abundance, the quick tags and the image browser, I create still here ... nice touch.
