This chapter describes the range of solutions, from Google and its partners, available for uploading data from an existing mail system to Google Apps. Data transfer is here the main issue and most of the chapter is dedicated to this topic. To this day, the most common mail systems are Microsoft Exchange and IBM Lotus Notes. One section is devoted to each. We review in each case the tools available for migration. The last part examines the remaining possibilities in a more generic way.
The migration phase is subject to the following prerequisites:
Once the prerequisites have been validated, the migration proceeds in three steps.
User account creation (see Chapter 7) followed by enabling and configuring Google Apps services are the first two steps of the migration. The last is data transfer.
