Migrations API

BuddyBoss and BuddyPress migration discovery, execution, and status polling.

Authentication

Migration routes are registered under AdminPolicy and should be treated as administrator-only operations.

Endpoints

Method	Path	Edition	Operation	What it does
GET	/migrations	Core	List Available Migrations	Returns the migration sources detected on this site — BuddyBoss or BuddyPress — as an empty list when neither is installed.
GET	/migrations/buddypress/config	Core	Get Buddypress Migration Config	Returns everything the migration wizard needs before it starts: the BuddyPress groups with their member counts and migrated state, the source data statistics, and any previously saved progress.
POST	/migrations/buddypress/start	Core	Start Buddypress Migration	Begins a BuddyPress or BuddyBoss migration by importing the groups as spaces and returns the progress record plus the maximum source ids the polling loop needs.
GET	/migrations/buddypress/status	Core	Get Buddypress Migration Status	Advances the migration by one time-boxed batch and returns the updated progress record — this endpoint does the work, it does not merely report on it.
