Does WP-Staging support BuddyPress?
Yes, WP Staging Pro supports BuddyPress. WP Staging Pro can clone the entire WordPress site including all BuddyPress data.
Push staging site to live without overwriting BuddyPress data
We did not test it yet but it seems BuddyPress stores all its data in certain tables prefixed by the bp_
So if there is BuddyPress user-generated content on the production website and you want to push your staging site to live will need to exclude first all database tables beginning with the prefix bp_before you push the staging website to the production website.
Otherwise, you would overwrite the BuddyPress generated content on the production website.
Before you start pushing your production site to live, we recommend that you verify this first and ensure that BuddyPress did not use any other tables, for instance like wp_posts/wp_postmeta.
Please get in contact with the BuddyPress developer if this instruction still works with their latest plugin version or if they changed something.
Also, make sure that you have a backup of live and staging site before you push the staging site to live.
