Phase 1: Prepare Source & Destination for Migrating from One O365 Tenant to Another
Tenant preparation has an important role in process of Office 365 migration; it will make the entire migration smooth & fast for you. Following steps are involved in the tenant preparation phase –
1: Domain Preparation:
In the domain migration process, one thing that is most important that is the domain can be attached to only one Tenant at a time. So before detaching the domain from the source tenant, we have to migrate data from domain to destination tenant, then detach the domain after that attach the domain in the destination Office 365 tenant. Follow the steps for Domain preparation:
- Start the domain verification process on the target tenant from the email domain.
- In the target tenant admin center, add a domain, and create text records in DNS (Domain Name System) for verification.
2: Schedule Office 365 Tenant to Tenant Migration:
In this step, we have to segregate users which we need to migrate source to destination tenant. To do this we will create a CSV file in which maintain the source & destination user’s email ID.
This CSV file will create a mapping between source & destination tenant users. Moreover, it will help us to perform tenant to tenant migration in Office 365 without a data mismatch issue.
3: Disable Directory Sync in Source Tenant before Migrating from One O365 Tenant to Another:
Disable active directory sync from the source tenant admin center. Once Active Directory Sync is disabled from the source tenant, any changes to the source tenant AD DS will no longer sync to Office 365.
This process will take 24 hours to complete, so you have to do this step before 24 hours of the tenant to tenant migration.
After preparation, we have to move on to the next steps in which we will migrate Office 365 tenant to tenant.
