Exchange to Office 365 migration

When moving from an on-premises Exchange environment to the cloud-based Office 365, there are many critical Exchange to Office 365 migration steps. The first decision is about process – will a cutover migration, an Office 365 staged migration or a hybrid migration to Office 365 best serve your needs. Next you'll need to think about how to protect your data during the transition, as some levels of protection may be lost during migration. You'll also need a plan to protect email data from loss and corruption as you migrate mailboxes, or you'll risk losing valuable information and intelligence in the move. Since migrations may involve downtime, you'll need a plan to accomplish the migration as quickly and unobtrusively as possible.
