This article will explain to you how to move Office 365 domain to another tenant with email data while keeping the same domain name.
Basically, this task will be divided into four major steps –
1 – Migrate Office 365 domain data to another tenant
2 – Detach domain from the old tenant
3 – Attach domain in the new tenant
4 – Migrate data from the same Office 365 tenant to the domain
Domain migration is necessary while performing Office 365 to Office 365 migration, the whole procedure is complicating itself to perform, but the most challenging task is detaching the domain from the old tenant and attaching it with the new tenant.
We have to detach domain from the old tenant before attaching to a new tenant because the domain cannot be attached to two tenants at a time.
One more thing, the detaching domain will take two days, we cannot attach the domain in a new tenant during this time.
Let’s start the process and keep these things in mind.
Step 1 – Migrate Office 365 Domain Data to Another Tenant
As we know the first step is to transfer Office 365 domain data to another tenant, but the question is how?
Currently, Microsoft does not provide any solution to do this task But, we can take the help of SysTools Migrator for Office 365 to Office 365.
With this software, we can easily migrate data from Office 365 domain to another tenant without any complications. Apart from this, it provides multiple facilities such as –
1 – Move emails, contact, calendar, documents.
2 – Concurrent migration option.
3 – Provides delta migration.
4 – Multiple options to Re-Run migration.
5 – Date-based filter option.
6 – User mapping option.

Download the software and follow the steps below to transfer Office 365 domain users’ data to another tenant.
In this step, we will move Office 365 domain users data in temporary accounts.
1.1 – Select Office 365 as a source and destination.
1.2 – Select the data that you want to migrate from Office 365 domain to another tenant.
1.3 – You can Enable Migrate domain permission & use group mapping option. The date filter option is also available to move selective data.

1.7 – After adding CSV file click on the Validate button to validate permission.
1.8 – Now, we are ready to migrate Office 365 domain data to another tenant, click on Start Migration.
Step 2 – Detach Domain from the old Tenant

2 – I’ll add the DNS records myself – if you choose this option, you have added DNS records yourself.
3.7: After that click on Finish.
4 – Migrate Data from the same Office 365 Tenant to the Domain
