I have WP 0.71 running in the "wordpress" directory using "b2xxxx" tables, and WP 1.0.1 running in parallel in "wordpress101" using "wp_xxx" tables. Now that my customization is almost done, I would like to import all the old data from the b2 tables to the wp tables. Unfortunately, phpMyAdmin balks with the error "Column count doesn't match value count at row 1" so I can't go that route.
Does upgrade.php provide the solution? I can't figure out what it does to the tables. I need to only import the data and not change anything to the customization in either installations, nor to prevent WP 0.71 from continuing to work while I finish my customization of the upgrade and test it.
