How to Migrate from Hosted Exchange to Exchange Online (Office 365)?
Migrating from On-premise to a new environment like office 365 is not an easy task. Hence knowing available options to do is an added benefit.
[Note: Choosing the right approach is as important as knowing]
The following section describes an approach that you can follow to move from hosted to Office 365. The mentioned approach is known as Minimal Hybrid Configuration. You can check the complete pre & post-migration checklist plan for Microsoft Office 365 here.
Technique A: Using Minimal Hybrid Configuration
Minimal Hybrid Configuration or Express migration is a simplified way of migrating mailbox data from hosted Exchange into Office 365. Using this method, users can avoid “Full Hybrid deployment” and perform the migration with minimum subset configuration. In this section, readers will come to know about the method of hosted exchange to O365 migration in only 6 steps.
Note: Minimal Hybrid Configuration can only be used if the user has never used a Full Hybrid deployment. If Full Hybrid deployment has ever been configured before, users will not see the Minimal Hybrid option in Hybrid Configuration Wizard.

Step 1: Domain Ownership Verification
The very first step of this migration is to verify the Office 365 domain you own. This step bears importance as Admins need to create email ids in the O365 environment for the users. Adding and verifying the on-premise domain is therefore essential before the beginning of the export process. Follow the steps mentioned here to complete this step:
a) Log in to your Office 365 account.
b) Navigate to Settings and choose the Domains option.
c) Click on Add domain located on the Domains page.
d) Domain wizard will open. Enter the domain name your organization uses in the on-premise Exchange Server, for example, contoso.com. Then click Next.
e) Select the TXT record tab to verify the domain. This option usually helps to verify ownership.
f) Once you have added TXT, wait for around 15 minutes. Then move to the next step.
g) Now click on Done>> Verify Now in the wizard. A verification page will open.
h) At this point, select I’ll manage my own DNS records option. End the process here and do not go to the next domain wizard step.
Step 2: Start Hosted Exchange Minimal Migration
Now, use global admin credentials to sign in to your Office 365 account. Make sure the system you are using is domain-joined to the hosted Exchange.
a) From the Admin center of Office 365, click Setup>> Data migration from the left pane.
b) Data Migration page will open, where you have to choose the Exchange option under the ‘Select your data service’ section.
c) Next, click on the Download application button to download Office 365 Hybrid Configuration Wizard and run it.
d) Click Next on the welcome screen of the Hybrid Configuration Wizard.
e) On the next page named On-premises Exchange Server Organization, keep the default values as they are. Only click on Next and the wizard will connect to Exchange Server by default.
f) Enter credentials for Hosted Exchange server and Exchange Server Online on the next page named Credentials. Click Next and the credentials will get validated.
g) On the next page termed Hybrid Features, click the radio button of Minimal Hybrid Configuration>> Next.
h) Click update on the Ready for Update page. This will prepare the hosted Exchange mailboxes for migration of Hosted Exchange 2013, 2010, and 2007 to Office 365.
Step 3: Provisioning Users
a) While you are on the User Provisioning page, enable the radio button beside “Synchronize my users and passwords one time (Recommended)”>> click Next.
At this stage, users will be asked to synchronize hosted Exchange with Office 365 by downloading and installing the Azure AD Connect wizard.
b) Download and run Azure AD Connect and then select Express setting default options.
When the synchronization is done, users will be redirected to the Data migration page of Office 365. On that page, all synchronized users will be visible. This is a one-time synchronization process and remains turned off for Office 365 accounts.
Step 4: Assign Users the Licenses of Office 365
At this stage, you have to assign users their Office 365 licenses. Then cloud mailboxes will get assigned to these users that will be used for importing hosted Exchange mailbox data. Like the given image, the requirement of a license will be indicated under the Status column on the Data migration page.
Go to Admin center>> Users>> Active users. Now assign licenses to the users.
Step 5: Initiate User Mailbox Migration
Since the part of assigning users, and their licenses are over, now you can start mailbox transfer by moving to the Data migration page. On that you, you need to perform these steps:
a) Click on the Setup option and then Data migration. Then click on Exchange.
b) Select the mailboxes you wish to migrate from hosted Exchange account to Office 365>> click on the Start Migration button.
Tips: To make sure that everything is working fine, initially migrate some mailboxes.
As the migration will take place, the progress status will be shown on the Data migration page.
Step 6: Update the Records of Public DNS
After the migration of mailboxes to Office 365 is done, change the MX record in order to point to Microsoft Office 365. The purpose of this step is to route all the new emails coming from this mailbox to Office 365. Users also have to complete the setup of different DNS records like CNAME, TXT, and SRV.
