Checking the Requirements

Migration Manager start to support scenarios supported by MAgE for migration to Microsoft Office 365 tenants where Basic Authentication is turned off after public update 20200813EX. This change is intended to support disabling Basic Authentication announced by Microsoft. By default, the Modern Authentication (based on OAuth 2.0) only will be used after this update is installed.

IMPORTANT: Please consider, after Basic Authentication is deprecated by Microsoft, public folder synchronization by legacy Exchange agents will no longer be supported. We recommend that you start using public folder synchronization by MAgE instead..

For details about the access privileges and software required for migration to Microsoft Office 365, refer to the following sections in the System Requirements and Access Rights document:

  • Migration to Microsoft Office 365
  • Directory Migration Agent
  • Accounts Used for Migrating to Office 365

To support mailbox migration to Microsoft Office 365 tenants by MAgE, Microsoft Office 365 plan should have the following features:
