Upgrading change.bbvx.org

I tried to use a scheme based on this process to upgrade change.bbvx.org

• Backup everything, verify backups
• Deactivate all plugins
• Move base directory to a different name and recreate the base directory
• Copy {.htaccess, wp-config.php, plugins, customized themes, uploaded files, images} to the new base directory
• Do the co to get the latest version
• Do the upgrade

Crashed with a blank screen. These were in the error log ... [Mon Mar 02 13:57:36 2009] [error] [client 24.225.78.32] WordPress database error Duplicate key name 'comment_approved' for query ALTER TABLE wp_comments ADD KEY comment_approved (comment_approved) made by wp_upgrade, make_db_current_silent, dbDelta, referer: http://change.bbvx.org/wp-admin/upgrade.php [Mon Mar 02 13:57:36 2009] [error] [client 24.225.78.32] WordPress database error Duplicate key name 'type_status_date' for query ALTER TABLE wp_posts ADD KEY type_status_date (post_type,post_status,post_date,ID) made by wp_upgrade, make_db_current_silent, dbDelta, referer: http://change.bbvx.org/wp-admin/upgrade.php

Reverted to

• Reload the backups. [checked that things work. yay.]
• Deactivate all plugins
• Delete everything that's not site specific.
• Download/unpack the latest version
• Do the upgrade

Seems to be working -- all plugins updated and activated.
