Allow O365 tenant migration
Could we please enable office 365 accounts to be migrated from one tenant to another. This is our situation here:
You can try Kernel Office 365 Migration tool to migrate mailboxes from One Office 365 tenant to another. https://www.nucleustechnologies.com/office-365-migration
This would be very convenient. We are a Microsoft Partner and are putting more and more of our clients on Office365. We just had a client that needed to move their domain out of an existing tenant and it was really a hassle due to the size of his mailbox.

You can use Migration Monster (www.migration-monster.com) for o365 tenant to tenant migration.

To migrate mailbox from one Office 365 tenant to another tenant Microsoft doesn't provide any solution, so the user needs to use third-party software. I have used this migration software - https://www.systoolsgroup.com/office365-express-migrator.html with this software I have migrated our mailboxes & shared mailboxes. You can try this tool.

Suggestion: Microsoft should come up with built-in tools to either merge Tenants or split Tenants. In the tools there should a feature to move the entire tenant to an existing tenant, because mergers are common these days. This should include: Exchange, Onedrive, Sharepoint and all other online features used by the originating tenant and move to the existing tenant. Same for splitting a tenant where one company domain will be moved to a new tenant, all objects associated with the domain should be moved to the new tenant with the same domain.

Microsoft is recommending to use third party tools for tenant to tenant migration is ridiculous. They should listen the user voice and understand the requirements.

I have just had a quote of £4500 to move 40 mailboxes 365 - 365 tenant only mailboxes and 2 one drives from a Microsoft 365 reseller. Not really very business minded get us all in and then held to ransom to move out without a lot of hassle.

D’Henri it s possible
What us the tool
It is too late for our migration, but this option is indeed a must with the big O365 community that it is now....
Absolutely ridiculous that Microsoft doesn't offer to migrate the data internally from region to region. Manual migration is going to be disaster.

No tenant to tenant migrations capability = lower consumption and slower digital transformation. We need an easy path for our customers to get back to business. Our customers are having to redirect resources and money from other digital transformation efforts.
I have done tenant to tenant migrations for years now and the process is still to use 3rd party tools and requires down time (while the vanity domian is removed from the old tenant tot he new tenant.) As i understand it, the tenancy is just a logical (parent) object for the customer and all services under it. As such, there needs to be method to change the tenancy of a customer. This would seem to be something that should be able to do with zero down time to the customer as long as there is administrative access to both tenants. As everything is in house it should be a process that is measured in minutes and not hours and should not involve 3rd party tools. Please put this into the roadmap.

I have done such a Migration as recommended by Microsoft Support Staff after I created a Support Request. I have been recommended to use the PST Migration and the Migration has been a disaster, although I am experienced with Office 365 an Migrations.
The PST Import did not import all Subfolders and Mails, so at the end I had to write powershell Scripts to count Items in all old Mailboxes and compare them to the new Mailboxes with Excel Formulas. As I said, absolut disaster! I then had to manually copy over several mails and folder that Customer had all his Mails again.
Also this PST Tenant to Tenant Migration is not possible without at least 15 minutes downtime in mails reception.
Please Microsoft, work out a Migration from Tenant to Tenant finally, as we have informed you already 4-5 years ago in a Special Circle about Office 365 Experience organised by Microsoft to do that!
We have around 20 users, and needed to change the subscription country for Office365. Microsoft advised me that the only option would be to create a new tenant, and migrate all users there. The effort and effects are the following:
- Migrate all mail, calendar, and onedrive with third party tooling
- Migrate all sharepoint data with third party tooling
- Remove the custom domain from all user accounts
- Delete all Office365 groups that were linked to our custom domain (though powershell)
- Remove all devices registered in exchange
- Remove all devices registered in Azure AD
- Block all existing users
- Transfer custom domain to new tenant, and link to all users to the new domain. All users will get essentially the same username, but with a different tenant.
This can all be done centrally.
The following will be a PER USER action however:
- After signing in with the user's 'new' account, after clicking Mail an error will show for around 30-45 minutes that the account cannot be found. Probably due to the need to create users on the onmicrosoft.com domain first in the new tennant, before changing their accounts to your custom domain.
- On mobile devices, e-mail accounts need to be deleted, and then added
- On Outlook desktop app, the old mail account needs to be deleted and than setup using the Office365 recovery assistant (http://diagnostics.office.com/#/Download?env=maven); any customizations (such as custom search folders) will need to be reapplied.
- Office2016 local installs need to be linked to new tenant (sign-in / sign-out required)
- OneDrive needs to be resynched on the users computer
- Last but not least, any domain joined PC's will need to delete the 'old' account from their PC and setup a new one.
I hope this will add to the arguments for creating functionality to change tenant ownership and country for Office365.

This is a critical feature. Existing migration tools work really well for Exchange to O365, Google to O365, and even IMAP to O365 with minimal down-time and no lost mail. But there is no way to migrate between tenants without engaging a third-party provider. This is necessary for acquisitions, but also for divestments, taking an entire domain and spitting it into it's own tenant. This process requires a third party, and even then the chances of lost mail are significant as it can take up to 2 days for the first tenant to release the domain before it can be added to the new tenant.

Need to be able to move between regions too!

For our company we need to unify of365 multiple subscriptions tu unique tenant. But doesn't exit any official procedure to do this, So I need to try/find it by myself.
I would like to be able to move from one data center to another. We added users from another country to our account so now the bulk of users has a poor sharepoint/onedrive experience. It would be better to migrate the tenant to a data center that lies between the two countries.

With more and more companies using Office365 and the natural habits of companies to execute mergers and acquisitions, the support of moving users and content between tenants looks like a must do for a cloud company Microsoft claims to be. What are your plans to support such a scenario. Can you put it on your roadmap.office.com?
