Office 365 tenant to tenant migration
The One-Stop-Shop for Your Office 365 Tenant Migration
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.
- 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 migrated, restructured and consolidated to support your new entity.
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.
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.
Get your tenant to tenant migration delivered at a fixed cost & using a pay-as-you-go SaaS model that reflects the workloads you need to move.
Cloud Essentials consolidated our two Office 365 tenants & 12 domains into a single tenant while minimising disruption to over 15,000 staff 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.
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.
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.
- Politics and security issues could prevent you from carrying out the optimal migration path – check out our latest video.
- 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.

The Cloud Essentials Azure-based platform combines the best solution for each of the many workloads you need to migrate, and can take into consideration any restrictions you might encounter, such as access rights between domains.
