Email migration is the method of transferring mailboxes, contacts, calendars and other data types from one platform to another. Organizations typically move from legacy email platforms to modern platforms. Choosing the right email migration method is critical as downtime, complexity, and risk during the transfer varies in different email migration methods.<\/p>\n\n\n\n

How do you choose the right email migration method?<\/h2>\n\n\n\n

Choosing the right method for email migration depends on the total number of mailboxes, data types that need to migrate, whether coexistence needed between old and new platforms and expected time window. Email migration professionals also measure the email server bandwidth and throttling to estimate approximate migration time.<\/p>\n\n\n\n

1. Cutover Migration<\/h2>\n\n\n\n

A cutover migration is a generic scenario in case of smaller number of mailboxes. Typically ranging up to 500 mailboxes. In the cutover migration, mailboxes are migrated at once to the destination server within a short window. Email migration experts plan the cutover migration during non-business days to ensure minimum impact on business. Execution mostly involves multiple machines or threads for time savings. At MailPro Pilot we usually target email migration done on a Friday evening through Sunday. And we use multiple virtual machines to parallel migration.<\/p>\n\n\n\n

2. Staged Migration<\/strong><\/h2>\n\n\n\n

This email migration method suits for large organizations or for the email server with bandwidth constraints. In a staged migration, the migration team moves mailboxes in batches over a defined period. The team divides the users into groups based on the organization\u2019s priority. Each group migrates separately to the destination platform. The process involves<\/p>\n\n\n\n
