Re: Buddypress upgrade 1.1.2 to 1.2.8
== Buddypress was not there nor was the section to configure it. ==
The Super/Network Admin has a separate new panel in WP 3.1. Click on Network Admin link in upper right hand corner and you’ll find the BuddyPress button in admin menu.
== OK but the site was totaly broken ==
Deactivate all plugins and change theme to default WP theme. Know that many BP plugins and themes from way back 1.1.2 are not compatible with current WP/BP versions.
== Do I need to upgrade a number of times ==
Nope. Just upload BP 1.2.8 and WP 3.1 manually i.e. via FTP or cpanel, etc. Access wp-admin, then go through the upgrade process. Btw, curious why not start from scratch?
