Sometimes Office 365 administrators need to migrate mailboxes from one tenant to another, but they don’t find any suitable ways for it. Though there are some manual approaches, they are very complex, and you won’t be able to perform it without proper guidance and technical knowledge. Many queries related to this can be found in Microsoft’s forums too.
So, here we are going to discuss some basics that can help you migrate mailboxes from one Office 365 tenant to another. Also, here we’ll talk about how you can plan the migration.
Migrate mailboxes, public folders, & archive mailboxes from one Office 365 tenant to another using a professional Kernel Office 365 Migration Tool.
The Office 365 tenant to tenant migration is performed using PowerShell scripts or third-party tools. Before that, there is an Office 365 Pre & Post Migration checklist you should keep in mind.
Prepare the domain with the following steps:
Make sure the domain is in use only one tenant. Otherwise, the verification will fail.
After performing these steps, it will take around 72 hours for the change to be seen.
Stop inbound mail flow to the source tenant by changing the primary MS record to an unreachable value or by using a third-party service. As you have noted the lowest value of TTL on MX record (of primary email domain) in your preparation step, you can plan the time of this step easily.
Before moving the Office 365 mailbox to another tenant, the primary mail domain should be erased from all objects in the source tenant.
It involves the verification of source tenant in the target domain (do one hour after the previous step).
Now it is time to decide on the migration method. You can also decide on the type and amount of data to be migrated. Migration can be accomplished using PowerShell scripts. However, third-party migration tools are recommended as they offer complete control over the migration.
