# BTAPPA

Bulk Transfer After Partial Portfolio Acquisition

A registry service for moving a group of domains from one registrar to another when only part of a registrar's portfolio changes hands, for example after a business sale. Registrants are told in advance, and the expiry dates stay the same. Each registry must have the service approved by ICANN.
