Things to You Need to Know About Tenant to Tenant Migration

Migration projects often result from mergers, acquisitions, or sales. If you’re considering starting a migration, or if you’re in the process of migrating from Office 365 to Office 365, you may not know where to start. Fortunately, such a transition is not as complicated as it looks.

Migrating from Office 365 to Office 365 differs from migrating from another platform to Office 365 in several important ways, so you need to understand the process before you start your migration project.

Why migrate from one O365 tenant to another?

Office 365 is now very mature in the market and has been used by many companies for a long time. In a natural business cycle, companies merge or acquire other companies or sell newly established businesses. As a result, we see much Migration from Tenant to Tenant projects.

For example, Company X (on O365) wants to acquire Company Y (also on O365) and integrate all IT systems. Alternatively, Company M (on O365) would have to sell the business unit that would be Company N (set up on O365) and move Company N’s users, data, and domains to their own tenant.

Because both entities are on the same platform, that is O365-Simply switch in the background and everything will be migrated. Unfortunately, this is not the case. Migrating from one O365 tenant to another is a complete migration project, much like migrating domains, users, mailboxes, and file content from your on-premises system to O365.

The more services you use with O365 such as SharePoint, the more it gets complicated. That is why businesses take some expertise to work with them to help in services like Migrate SharePoint from one Tenant to Another Tenant for the smooth process of migration without any complications.

Complications of O365 to O365 migrations

There are additionally very important issues that make migrating from O365 to O365 more difficult than migrating from on-premises to O365. The domain you are migrating can only exist on one O365 client.

If you are currently using some domain with O365 Tenant X and you want to migrate that domain, mailbox, or user to O365 Tenant Y, delete or rename all objects before adding the domain to Tenant Y. You need to remove the domain for tenant X (such as mailboxes, user accounts, O365 groups that use this domain from tenant X, etc.) and have the O365 platform detect that the domain is not associated with any tenant. You can wait and then add them to tenant Y to create an object in that domain.

For mailbox and user migration, use wildcard names to create users and mailboxes in the target tenant (that is, without the domain you are migrating) while the users continue to work. Use the tool to copy the contents of the mailbox to the Source tenant. During the cutover, all objects on the source tenant are renamed, no longer pointing to the domain to migrate, the domain is removed, and then it is added to the target tenant. At this point, objects with wildcard names (users, mailboxes, etc.) will be renamed to the same names used by the source tenant.
