Migration from one tenant to tenant is a normal thing, and reasons like company mergers, acquisitions, initiate this. Migration of mailboxes from one Office 365 tenant to another Office 365 Tenant is not an easy task if you do it manually. Users face many hurdles while doing the Office 365 Tenant to Tenant migration by the PowerShell script and the manual method. The Microsoft 365 Tenant to Tenant migration can’t be accomplished without completing the pre-migration tasks. Here, we will know all about the basics that one should know before the migration and Office 365 tenant-to-tenant migration best practices.
Office 365 Tenant-to-Tenant Migration Checklist:
1. Domain Preparation: Users must prepare the domain by checking the following tasks
- Firstly, verify the license of the target Office 365 and its validity.
- Create admin accounts in Source and Target
- Moreover, in the target Office 365, create the user mailboxes, distribution groups, and room/resource mailboxes
- Synchronise the target domain with the source domain using AD DS tools.
2. Domain Verification
- Verify the target tenant domain in MS Office 365.
- In the target admin center, add the source domain and create the TXT record in the Domain Name System (DNS).
- It will take 72 hours to show the alteration. Be sure that the domain is used in only one tenant.
3. Schedule the Migration
- Have a list of user mailboxes that have to be migrated, and for mapping, create a CSV file.
- Know the lowest value of TTL on the MX record. It will determine the time that takes place to go into effect after making any change.
- From the MS Office 365 admin center, disable the directory synchronization for the source tenant.
Migration Tasks:
1. Halt inbound mail flow
Change the primary MS record to an unreachable value to stop the inbound mail flow to the source tenant.
2. Prepare the source tenant
Erase the primary mail domain from all objects in the source tenant
3. Prepare the target domain
Verify the source domain in the target domain
- When using Active Directory Federation Services (ADFS), you have to configure a new domain in the target tenant for ADFS.
- Now, activate the new user accounts in the target domain and assign the license
- After this, set the source domain as the primary email address for the new users.
- By this, you are capable of routing the emails to the new mailboxes.
- Now you can go for the mail flow from or to the source and target tenant.
By doing all the pre-migration and migration tasks, choose the migration method. Satisfactory migration can’t be done by the PowerShell Scripts. So, it is good to go with the third-party professional tool.
