Office 365 tenant to tenant migration
The One-Stop-Shop for Your Office 365 Re-organisation
In the event of a merger, acquisition or just a change in the way you want to organise your business, you can now migrate virtually any workload between Microsoft Office 365 tenants.
On ‘day one’, everything needed for smooth collaboration between your domains is established, ensuring business as usual for all staff and seamless communications with the outside world from the new entity.
You can then migrate the widest range of different workloads you’re likely to encounter as a one-stop-shop, including:
- Mailboxes, SharePoint, Teams & Groups, OneDrive for Business, Public Folders, Skype for Business (including conversation history), Stream, etc
- Third-party email archives & email journals
- G Suite & IMAP mailstores
- Document management systems, Power BI & Power Apps
As part of your migration Active Directory can also be restructured to support your new entity.
Making sure that your security and data governance isn’t compromised as you migrate is also an essential part of the service.
There’s no need for any servers on your environment as your migration is done using our SaaS Migration Platform in Azure, ensuring optimal security and performance.
During your migration you’ll work closely with our services team, receiving the best expert advice and a personal and responsive service we believe is unrivalled.
Get your tenant to tenant migration delivered at a fixed cost & using a pay-as-you-go SaaS model that reflects exactly the workloads you need to move.
Cloud Essentials unified and consolidated our two Office 365 tenants and 12 domains into a single tenant while minimising disruption to over 15,000 staff in offices around the world.
STOP PRESS: Microsoft recently announced their tenant to tenant mailbox move capability, which is suitable for just moving mailboxes for less than 500 users. Get in touch to discuss the additional services we can offer as your Office 365 partner.
Merge, split or move between Office 365 tenants
When you need to migrate or merge Office 365 tenants, moving data and users is just the tip of the iceberg, especially if you have multiple domains that must co-exist for any length of time.
- You need to synchronise contacts and free/busy information to ensure co-workers can email and collaborate easily and communicate with clients throughout the migration – as though in a single domain.
- You may need to consolidate the infrastructure of the merging organisations, starting with integrating the separate Active Directory (AD) instances into one.
- Not all the organisations involved may be in the cloud – we often work with enterprises that need to integrate legacy on-premises users and applications with Office 365.
- There may be incompatible email archives and journals that need to be merged.
There’s other things to transfer across and rationalise, including security, privacy, anti-spam, legal holds and retention management policies.
Let Cloud Essentials take the complexity out of your Tenant merger or migration. We can split the different workloads into into separate migrations and do a mix and match of whatever part you need.

You can choose to keep or overwrite existing files at the OneDrive for Business or SharePoint destination, as well as whether to migrate metadata such as file creation details.
