Prepare for your Transition from EHA to Office 365.
You need to prepare for your migration from EHA to Office 365. Actions you will perform depend on the type of mail system configuration your company uses. Please select the configuration that most closely aligns with your company's configuration:

On-Premise - This configuration means you manage your own e-mail servers at your company. This is the mail system that your employees use day to day as their e-mail inbox. You do not have employees logon to Office 365 to read their daily e-mail. Click here for more information about migrating to EHA if all your mailboxes are on your On-Premise mail servers.

Hybrid - This configuration means you have a mix of both On-Premise and Online mailboxes.
