Re: How to Install BuddyPress to Existing WordPress Install?
I would like to install buddypress onto my existing wordpress install (regular wordpress not wordpress mu).
At this time, BuddyPress only works with WPMU 2.7.1. You cannot use it with single-version WordPress.
How would I upgrade this to a wordpress mu/buddypress install?
will this integrate with my current wordpress theme
No. You will either need to use the standard BuddyPress themes that come with the package, or update your custom themes as detailed here: https://codex.buddypress.org/getting-started/installing-buddypress/upgrading-from-rc-1/
