Once you’ve registered source and target environments and set up mappings, you’re ready to begin creating waves.

What’s a wave?

We call a set (or batch) of source/target mappings a “wave”. For example, let’s say Office 365 data is being moved from one tenant to another following a merger. As part of that project, we want to set up a wave where all of the sales and marketing departments’ data gets migrated together to the new tenant. Then, when that wave is complete, we’ll start migrating the next wave where the finance and operations departments’ data is moved. A migration project consists of multiple waves. When one wave is complete, you’ll start another. The eventual result is that the waves move the entire organization’s data the source to the target. Here’s how it looks:

Creating and starting a wave

Follow the steps below to create a wave.
Note: Before you create a wave, you must register source/target tenants, create migration pairs, enable coexistence, and map mailboxes. You also need to a plan/strategy for your waves (a plan of which accounts you’ll move in each wave).

  1. In the left menu, select Waves > Exchange.
  2. Click Add.
  3. Select an Environment Pair.
  4. Enter a Wave Name.
  5. Click Select a File and browse for the csv format wave file.
  6. Click Add.
  7. By default, waves start in the Not Started status. Click the top right button (shown below) and select Start Now to start migrating the wave.
