On Demand Migration Current - Hybrid Exchange User Guide

Test and Pilot Migrations

Any full scale migration should be preceded by test and pilot migrations, to confirm that your migration processes and procedures will accommodate the organization requirements.

  • A test migration uses real users and real data in a segregated test environment, or dummy users and dummy data in your live production environment.
  • A pilot migration uses a small portion of real users and real data in the live production environment.

In either case - a test or pilot migration - the data to be migrated should be a representative sample of the production data, and the test or pilot migration should be run with the Quest applications set for the same configuration and process options that you intend to use for the production migration. it is recommended to select test or pilot users whose usage and data types make them representative of the total user population. Then create and run matching / migration tasks for those accounts, including all range of tasks you are planning to perform. When the tasks are completed, review errors and warnings, if any. See Event Management section for more information.

Quest recommends that you use both test and pilot migrations:

Perform one or more test migrations in a separate test environment, migrating test copies of real users and their real data. The separate test environment ensures that no test process will affect the data or configurations of your production environment. If a test exposes any problems under migration, you can make amendments and then repeat the test by simply dumping the test environment and recreating it from scratch.

When you are confident that your test migrations have sufficiently refined your planned migration, perform a pilot migration for 20 or 30 users to verify if your planned migration is satisfactory for your "real world."

Project Management

A migration project contains the full set of migration features and provides a summary of all the migration activities in the project dashboard. You can work with a single migration project or you can set up multiple migration projects to split staggered migration plans into manageable projects.

In this topic:

Creating a new migration project

  1. Sign in to Quest On Demand.
  2. From the navigation pane, click Migration to open the Migration projects view.

  3. Click Create Project.

    8. Hybrid Modern Authentication (HMA) - this option appears when you choose Microsoft Exchange 2010-2019 as the source or target. Select this option to allow the On Demand service principal to access mailboxes, which are hosted on-premises, by using authorization tokens obtained from the source or target tenant. When you select this option, the following settings are also considered:
