Upgrade to 1.0

Ok, count me among those that can’t upgrade smoothly. Was running 0.71. Uploaded the new 1.0 files into the appropriate folders and ran upgrade.php. Got the “you don’t seem to have run install.php” message, so I tried that. Still could not see my posts. So I deleted all the WordPress files on my server and uploaded a clean copy, changing wp-config.php to show my database name, etc. Ran install.php. Got to running, but only with the “hello world” default first post for WordPress. Looked at my database. I now have all my b2….. as well as wp…… tables. Does anyone know how to transfer the *data* for my posts, users, categories, etc., from the b2….. tables to the wp…… tables? Any help would be appreciated.
