Pre-Migration Preparatory Steps
When it comes to migrating from Exchange 2016 to Exchange Online, the first step is always preparation. It’s important to plan beforehand, so you are certain of the processes involved and your timeline for completing the migration.
Here are a few pre-migration preparatory steps worth considering:
- Double-check that all user accounts and mailboxes in your on-premises environment are up to date and valid.
- Make sure Windows PowerShell is installed on each computer used by end users.
- Create a list of all mail objects within Exchange Server and their associated permissions.
- Identify any customizations or applications that are dependent on the source email infrastructure, such as Outlook forms and custom applications.
- Test the Quality of Service (QoS) performance of your network connections between source and destination environments.
Thoroughly completing each of these steps will ensure that the process of migrating from an on-premises Exchange 2016 instance to Exchange Online runs smoothly—and without any unexpected surprises!
Setting Up Your Exchange Online Environment
Before you can migrate data from Exchange 2016 to Exchange Online, there are a few steps you need to follow in order to ensure a successful migration. First and foremost, you will need to set up your Exchange Online environment. This includes tasks like configuring mail flow and user accounts, setting up permissions and address books, as well as activating features like anti-spam protection.
Once all of this is done, you’ll be ready to begin the process of migrating your data. You’ll want to make sure that everything is properly configured before moving on – if something’s not right, it can lead to problems down the road that could derail your migration efforts.
To make sure things run smoothly, you should also be aware of potential pitfalls like Exchange Web Services throttling, mailbox size and item count limits, as well as issues related to service availability. By taking the time to go through each of these steps before starting your migration process, you can minimize the chances of any migration hiccups and make sure that everything runs smoothly.
Setting Up Users for the Migration
Migrating to Exchange Online is a complex process that requires a robust planning and execution process. One important step in the process is setting up users for the migration, making it easier for them to begin accessing their mailboxes and calendar information in the cloud.
Here are the steps you need to take to set up users for the migration:
- Create new Exchange Online mailboxes in Office 365: This step involves creating new mailboxes in your Office 365 environment and adding them to relevant Office 365 groups. You’ll need to create new mailboxes even if you intend to migrate existing on-premises Exchange 2016 users.
- Set upautodiscoverrecord: To ensure that users can access their mailboxes after the migration, you’ll need to create an autodiscover record in your on-premises Active Directory infrastructure that points your Exchange Online domain name. This will ensure that Outlook clients can locate the Exchange Online environment and quickly connect with it.
- Configure Outlook profiles: Finally, you’ll need to set up Outlook profiles and configure access permissions for all of your migrated users. This will ensure that each user’s mailbox is configured properly so they can access their calendars, contacts, and other data stored within the mailbox.
By following these steps, you can make sure all of your Exchange 2016 mailboxes are set up correctly for successful migration over to Exchange Online — ensuring a smooth transition of data from on-premises servers over to cloud infrastructure.
Running the Migration Batch and Verifying Its Completion
Whether you’re migrating from Exchange 2016 to Exchange Online or from any other platform, the process is fairly straightforward. You’ll want to create a migration batch, which is essentially a list of mailboxes that you want to migrate in the form of a CSV file.
Once your batch is created, you can load it up and start the migration process—and if needed, you can easily pause or stop it at any time. Depending on the size of your organization and the amount of data you’re migrating, it could take anywhere from a few hours to several days. Once it’s done, you should check to verify that the migration has been successful by comparing User Mailbox Status Reports and checking for errors.
To ensure everything went smoothly, make sure that:
- All user mailboxes have been listed in the final report as successfully migrated
- The synchronization status of each mailbox reflects as “Synced with Exchange”
- All users’ mailboxes have been configured properly and ready for use in Outlook or OWA (Outlook Web Access)
Once all these details are verified and confirmed, then your organization is officially ready to enjoy all the benefits of Exchange Online!
