Stage 1 (domain preparation): confirm Office 365 licensing on the target, create admin accounts on both source and target, create mailboxes, room and resource mailboxes, and distribution groups on the target, run AD DS consolidation if needed, and train users on the new tenant. Stage 2 (domain verification): verify the target tenant domain and add the source domain as a custom domain via DNS TXT record. Stage 3 (schedule migration): build a CSV mapping user mailboxes, lower the MX record TTL on the primary domain, and disable directory sync on the source from the Microsoft 365 admin center to stop further AD DS sync; allow at least 24 hours. Stage 4 (cutover): redirect inbound mail by changing the MX record, remove the primary domain from source-tenant objects (default email, Lync licenses, distribution lists, secondary addresses via Get-MsolUser), then verify the source domain on the target, configure auto-discover CNAME and AD FS, activate users with new passwords, and switch the MX record to Office 365.

In this post, [Migrate Office 365 tenant to tenant](/content/office-365-tenant-to-tenant-migration/office-365-migration-services), we are going to discuss various scenarios for tenant to tenant migration, **benefits** of tenant to tenant migration, and step by step [tenant to tenant migration](/). ## Why do users need Office 365 tenant to tenant migration? The Office 365 suite owned by a site is linked to a renter. As a tenant of Office 365, we retain all the **data stacks**, such as _SharePoint, OneDrive, and [Yammer](https://www.businessinsider.com/guides/tech/what-is-yammer-app)_. This publishing platform can allow multiple distinct data sources, such as Exchange Server data (which stores email communications) and Active Directory data, to sit **together under one roof**. [![Office 365 tenant to tenant migration](https://media.mailhop.org/duocircle/images/2022/07/check-DMARC-record-1018.jpg)](https://media.mailhop.org/duocircle/images/2022/07/check-DMARC-record-1018.jpg) ## Challenges users will face while migrating from One office 365 tenant to another ? Users are encountering a number of [challenges](/content/office-365-tenant-to-tenant-migration/office-365-tenant-to-tenant-migration-onedrive) when completing this task. Some of them are mentioned here: 1. This O365 tenant-to-subtenant migration is a **difficult** and **tedious** process. Users will need to undergo a lot of difficulties while executing this operation. 2. One of the biggest issues leading this operation is keeping the [information integrity](https://www.talend.com/resources/what-is-data-integrity/). 3. Executing the steps correctly is a necessity for **maintaining information integrity**. People may experience [data loss](https://www.techopedia.com/definition/29863/data-loss) during the process. [![](https://media.mailhop.org/duocircle/images/2023/11/Office-365-Migration-Statistics.jpg)](https://media.mailhop.org/duocircle/images/2023/11/Office-365-Migration-Statistics.jpg) ## Migration planning from start to end ### Step 1: Domain preparation Now, users must follow these steps for a smooth [Office 365 migration](/content/office-365-migration-to-office-365): 1. Make sure that you have your **Office 365 license prepared.** 2. Then, **create admin accounts** in both the source and target for easier migration. 3. Then, users must create mailboxes, room resource mailboxes, and distribution groups in the target. 4. Apply AD DS consolidation using [AD DS tools](https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/ad-ds-getting-started) and synchronize source and destination domains if needed. 5. It is essential to **train employees** regarding how to use Microsoft 365 after migration. ### Step 2: Domain Verification 1. 365 is authenticating your **target tenant domain**. 2. Then, input the source Microsoft 365 domain in your target admin center for **DNS-based TXT records.** ### Step 3: Schedule Migration 1. First, make a list of **user mailboxes** that are required for migration and for mapping, create a [.csv file](https://www.businessinsider.com/guides/tech/what-is-csv-file). 2. Write down the minimal value of **TTL** on the [MX record](https://www.cloudflare.com/en-in/learning/dns/dns-records/dns-mx-record/) (of the primary email address domain). Hold off on **directory sync** for the source tenant (from Microsoft 365 admin center) in order to stop any sync changes in source tenant AD DS to Microsoft 365. 3. In Microsoft 365 admin center, disable directory sync for the source tenant to prevent the syncing of any modifications to source tenant account **ADFS 2 to Microsoft 365 cloud.** _Minimum 24 hours will be required until this process is complete._ [![DuoCircle infographic](https://media.mailhop.org/duocircle/images/2024/07/Office-365-Migration-Statistics.jpg)](https://media.mailhop.org/duocircle/images/2024/07/Office-365-Migration-Statistics.jpg) ### Step 4: Migration stage **Top** **inbound mail flow:** Interrupt inbound mail flow to the recipient by changing your primary **MX record to a value of -1** or by removing a third-party application. Since projection done in the preparation phase for the designated lowest value of [TTL](https://www.namecheap.com/guru-guides/what-is-time-to-live-ttl/) on the MX record of your primary domain shows, you should be able to plan this step. - **Preparing source tenant:** Before you move your enterprise 365 mailbox to yet another tenant, the principal mail domain must be erased from every one of the objects in the source tenant. - - Reset the default email address to the origin email address of [Microsoft Office 365](/content/office-365-cloud-migration). - _Remove all the Lync licenses from the source tenant using the Lync Admin Portal._ - Then, reset the default email address of distribution lists, rooms, resources to the initial domain. - From all tenants remove all the secondary email addresses In the Windows [PowerShell](https://www.bleepingcomputer.com/news/microsoft/microsoft-powershell-lets-you-track-windows-registry-changes/), run the command **Get-MsolUser -DomainName** xyz.com to retrieve all of the boxes that are still using the primary email address or refusing to remove. - **Preparation of target domain:** Verifying the source tenant in the desired domain is the place where this process begins. - - Continue reading Configuring auto-discover [CNAME](https://en.wikipedia.org/wiki/CNAME%5Frecord). - Then configure a new domain name in the target tenant for AD FS. - Now, **activate the newly-created user accounts** in the desired domain and then assign licenses. - Create a **source domain** as the main email address for those who are new to the app. In addition, share the passwords with the end users. - Once the user mailboxes are active, change the mail delivery setting and point the **MX record to the Office 365 address**. Then, **test mail flows** out and in of the target tenant. In conclusion, Migrating tenant to tenant in [Office 365](https://www.news18.com/news/tech/office-365-is-now-microsoft-365-with-office-apps-and-more-new-microsoft-is-all-about-consumers-2586037.html) is convenient and straightforward. The steps involve exporting **tenant data**, transferring data to the new tenant, **configuring global settings**, and applying roles. ## Topics NewsSecurityUpdates ![Brad Slavin](https://media.mailhop.org/dmarcreport/images/team/brad-slavin.jpg) Brad Slavin General Manager General Manager at DuoCircle.
