To help us get up to speed quickly and run the pilot smoothly, we partnered with Appirio Consulting. Appirio had previous experience converting large corporations from Lotus Notes/Domino to Google Apps. Appirio conducted one-on-one or small group training sessions for the pilot users and targeted training for the executive admins because of the complexity of their jobs when it comes to collaboration, email, and calendar management.
