Hybrid Migration Scenarios

This topic contains a collection of supported by Migration Manager migration scenarios that involve hybrid deployments. For guidance on the choice of scenario, examine the descriptions to find the route that is most appropriate for you.

Currently, Migration Manager supports the following hybrid migration scenarios:

• Acquisition with a Hybrid
• Complex Acquisition with a Hybrid
• Reorganization or Upgrade with a Hybrid
• Complex Reorganization or Upgrade with a Hybrid

Keeping existing domain name

1. All described migration scenarios imply that the domain name for the migrated objects will be changed during migration. However if you want to keep the existing domain name, take the following steps:
2. Migrate objects from the original domain to a temporary domain using Migration Manager for Active Directory. The name of the temporary domain must differ from the name of the original domain.
3. After that perform another migration according to the chosen hybrid migration scenario. Be sure to have the destination domain name the same as the original domain name.

After performing such two-hop migration, you will implement the desired migration scenario and the migrated objects will have the same domain name as the corresponding source objects.

Acquisition with a Hybrid

The goal of this migration is to merge objects from the source environment into the target hybrid environment. This also entails a change of domain name for the objects that are migrated. The primary SMTP addresses for the objects from the source environment are to be changed to match the target ones.

The typical use case for this scenario is when one company buys another, and the newly-acquired company needs to merge in its directory and mail system.

Migration Manager provides an ability to migrate users' mailboxes from the acquired company directly to Microsoft Office 365 without the need to firstly migrate mailboxes to on-premises Exchange organization.

Prerequisites

• The source environment is a regular Active Directory domain with an Exchange organization.
• The target environment is an Exchange hybrid deployment.

Procedure

Pre-migration task: Establish Mail Flow to Source Exchange Organization

1. On-Premises Directory Migration
2. On-Premises Mailbox Migration
3. Cloud Directory Migration
4. User Matching
5. Cloud Mailbox Migration
