Office 365 tenant to tenant migrations & co-existence

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 also 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 – so there may be added complexity in integrating on-premises users and applications.

There’s other things to transfer across and rationalise, including security, privacy, anti-spam, legal holds and retention management policies.

In fact, the amount of up-front planning, project management, communication and post-migration clean-up activities involved to ensure a fault-free tenant migration can be daunting, with no ‘one size fits all’ third-party solution and no off-the-shelf solution from Microsoft*.

Cloud Essentials combines best-of-breed solutions with expert services to assist with your tenant to tenant migrations, including Mailbox, SharePoint & OneDrive moves, synchronisation and merging of infrastructure and the seamless switching of services such as email and Teams.

*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.
