Exchange Server has been used for a long time all over the globe, but over time, the market has been tilted toward Office 365. Office 365 is a one-stop solution that offers multiple applications and services within a single subscription. Office 365, a cloud-based software as a service, attracts a lot of users, and all are searching for a way to migrate Exchange mailboxes to Office 365.
This write-up will cover all the manual ways and an alternative professional solution. Also, below, I have listed reasons for users to choose Office 365 over the Exchange Server.
Why Users Migrate from Exchange Server to Office 365
- One-Stop Platform: Office 365 is a subscription-based service that enables you to include a range of essential modern applications in your subscription. With Office 365, you can subscribe to Microsoft Office products (such as PowerPoint and Word), SharePoint, Outlook, Teams, Yammer, and more.
- Zero Downtime: Office 365 offers an impressive auto-update feature, ensuring it automatically updates to the latest version without any downtime, allowing you to use your account without interruptions.
- Accessibility: Office 365 operates in the cloud, eliminating the need for software or hardware installations. You can access it with a single tap, even on your smartphone, anywhere worldwide, whether during a vacation, a road trip, or any event.
- No End-of-Life Concerns: Unlike Exchange Server, which has a 10-year lifespan, Office 365 has no end-of-life concerns. You won’t need to update your Office 365 version every 10 years.
- Infrastructure Cost Savings: Office 365 has subscription plans addressing the needs of every end user.Office 365 is a cloud-based service; hence, there is no need to deploy the hardware machinery and all to get the benefits.
Manual Ways to Export Exchange Mailboxes to Office 365
1) Staged Migration:
As its name clarifies, this method to migrate Exchange mailbox to Office 365 is completed in stages (two or more). Usually, medium-sized and large enterprises use this method.
In the first stage of staged migration, migrate the data of a specific date range. After relocating in the first phase, domain transfer and MX record updating occur.
After enabling the domain in Office 365, migrate the remaining data.
Checks Before Moving for the Staged Migration:
- Cross-check that the On-Premise Domain and Office 365 domains are identical.
- Create and sync On-Premise users in Office 365. You can use Microsoft Azure Active Directory Sync Service.
- List up the On-Premise Exchange user list. For the migration batch, use the CSV file to list the users.
- Create an Outlook Anywhere migration endpoint that will be needed for each migration batch.
Steps to Migrate Exchange to Office 365: Staged Migration
- Go to Exchange Admin Centre >> Recipients >> Migration.
- Click on the (+) New icon and choose Migrate to Exchange Online.
- Select Staged Migration as the migration type and click on Next.
- Now, please select the desired CSV file for the migration batch and validate it.
- Must authenticate the migration endpoint information and then click on Next.
- Under the Move Configuration >> enter the migration batch name >> Next.
- Select the Auto Start or Manual Start. Using the New button, create the Migration batch.
- Again, visit Exchange Admin Centre >> Recipients >> select Migration.
- On the migration dashboard, select the batch >> Start.
- You will get a Syncing Status on the dashboard as migration initiates.
2) Hybrid Migration: What, When, and How?
Hybrid Migration is when you use both on-premises and Office 365 cloud. Creating a hybrid setup is more like a bridge when you migrate mailbox items to Office 365, and your Azure Directory is still connected.
Detailed Steps to Migrate Exchange to Office 365:
Creation of Endpoint
Creating endpoints is a crucial step as it consists of connection settings for the On-Premises Exchange Server that runs the MRS proxy.
Enable Proxy Service
If the proxy service is not enabled, then you must enable it. Follow the below steps for the same:
- Open the Exchange Admin Centre.
- Servers >> Virtual Directories >> Client Access Server.
- Now, make a selection for the EWS virtual directory.
- Make a click on the Edit.
- Check the “Enable MRS Proxy Endpoint” and click on the Save.
Configure Hybrid Environment: Establish a hybrid configuration between the on-premises Exchange servers and Office 365. This enables secure communication and allows for a seamless coexistence.
Migrate Mailboxes: Select specific mailboxes or groups of mailboxes to be migrated from the on-premises Exchange environment to Office 365. This can be done using the Exchange Admin Center or PowerShell commands.
Manage Coexistence: During the hybrid migration, users can access their mailboxes either in the on-premises Exchange environment or Office 365, depending on their migration status. The hybrid environment ensures synchronized access and synchronization of mailbox data.
Complete the Migration: Monitor the migration progress and ensure that all desired mailboxes have been successfully migrated to Office 365. Gradually increase the number of mailboxes in Office 365 until the entire organization is migrated.
3) Cutover Migration:
Cutover Migration is simply the migration in one go. It is best for the small level businesses that have a limited number of mailboxes. Cutover migration asks to fulfill prerequisites before moving for the migration.
After completing all the formalities, just follow the below-mentioned steps:
- Open Exchange Admin Center, select Recipients, followed by Migration.
- Then go to File > New > Exchange Online Migration.
- Select Cutover Migration as a migration type and click on the Next button.
- A page detailing migration endpoint information will load. Before moving on, please double-check the details you’ve entered.
- In the Batch Name field on the Move Configuration page, enter the name of the migrating batch, and then click Next. On Migration, you may see the batch name in the list.
- Following that, choose an option on the Start the batch.
• Begin the batch processing immediately: If a new migration batch is available in a Syncing state, it will start processing immediately.
• Schedule the process for a later time: The status of the migration batch is set to Created, but no migration has yet begun. Select the desired migration batch from the dashboard, and then click on Start to begin.
- To start a new batch of migrations, select New from the menu.
Once you create the migration batch, it will be visible on the migration dashboard. In order to finish the process, you must now initiate the cutover migration batch.
