Re: How to migrate BuddyPress from WordPress Mu to WordPress
If you just care about your BP data, export all database tables with “wp_bp_” prefixed in them, as well as the “wp_users” and”wp_usermeta” tables.
Preferably try this on a new install of standard WP with BP installed on a local testbox.
Then try importing the tables you exported above into your testbox’s db.
Disclaimer: This is all theoretical!
There might be a few things you need to manually change in the SQL export, but I’m not sure at this point.
Also, hope you’re not using user blogs on WPMU!
