So, you finally did it. You’ve decided to take the plunge and migrate your business communications to the Microsoft Office 365 clouds. This move will boost productivity, increase flexibility and improve agility. To ensure you get these benefits and more from the move, there are recommended Office 365 migration steps that come directly from Microsoft. If you decide to go it alone, these are the high-level steps:

1. Determine Your Migration Method

There are three main migration methods to choose from.  Generally, most customers run hybrid migrations if they move to Office 365 from Exchange on-premises. It is essential to prepare the migration environment before any active data is migrated. Also consider, in a geographically dispersed organization (and/or Microsoft 365 Multi-Geo Tenants) that a number of MRS endpoints may be set-up: you should aim for at least one per geography where your organization has Exchange servers.

2. Deploy Hybrid


The Hybrid Configuration Wizard will assist you in creating the environment ready for your migration. Once completed, if time has passed since it was initially set up, it’s well worth reviewing the configuration before starting on your migration journey.

3. Create User Batches (or Waves / Lists)

To start, your migration batches will most likely consist of a small number of test users – once those are migrated you’ll be ready to ramp up to larger number of users. Each customer is different when it comes to how batches (or lists) are created. 

4. Migrate the Batches

The migration can be performed in the Office 365 Admin Center, or via PowerShell. A key aspect is whether the batch will be automatically or manually completed. If you choose manual completion Exchange will migrate 95% of the mail to Office 365 and periodically migrate any additional mails keeping the target at 95% of the source until you manually complete the batch. 

5. Assign Licenses


Generally speaking, you have about 30 days to assign licenses to users. This is one of the most important steps. Failure to complete it could undo all your hard work, because the mailboxes will be disabled after the grace period of 30 days expires. As we’ve discussed before it’s important to consider the different types of users in your organization and match with appropriate license types.

There is a 'but'!

These Office 365 migration steps offer a simplified explanation of a far more complex process. Here are some examples of common overlooked steps critical for a successful migration:

  • User communication – Migrations where users receive little or no proactive communication often lead to confusion, service disruption, and in some cases, many days where users can no longer productively complete work-related tasks.
  • Automation – Doing the above steps for 100 users is repetitive and cumbersome enough, but what’s that like for companies with 1000, 5000, 10000 or more users to migrate?
  • Many, many, many other workflow steps – whilst the above is at a high level the bare minimum, in most organizations there will be on-premise legacy archive data to migrate, clean-up of legacy shortcuts (or stubs) in users’ mailboxes, distribution or security group membership changes, and more. In fact, even a simple template might look more like this:
