Office 365 is a cloud-based service that enables businesses of all sizes to collaborate and communicate more efficiently. It offers numerous functionalities such as email hosting, file sharing, video conferencing, etc. However, as organizations grow or merge with other companies, they may need to migrate their data from one tenant to another.
What is Cross-Tenant Mailbox Migration?
Cross-tenant migration refers to the process of moving data from one Microsoft tenant (Office 365 subscription or instance) to another while retaining all original settings and data formats. This process can be complicated because each tenant has its unique configuration settings regarding domains, security groups, user’s roles & permissions.
How does Cross Tenant Migration Works?
The cross-tenant migration process involves several critical steps that must be carried out carefully for it not only move smoothly but also minimize any risks associated with lost files/error transfers/other issues. You can contact CloudBik, third party migration service provider to perform the migration for you or use the Microsoft 365 migration tab to migrate mailbox data manually. Below are some step that one should consider while performing cross-tenant mailbox migration.
Planning Phase
The first phase involves laying out the groundwork for your project by answering questions like what needs migrating? What challenges do we anticipate? Identifying the reason for migration is also essential, as it will dictate how much data you need to transfer.
Preparation Phase
In this phase, you will prepare both your source and target tenant. You should archive old files, clean up any unused data that might slow down the transfer process and configure settings that ensure optimal performance. Create an inventory list of user’s identities such as usernames & passwords, email addresses & user groups to avoid leaving out vital team members or causing confusion on their end.
Execution Phase
The third phase involves beginning the actual migration process with Microsoft 365 Migration Tab and Windows PowerShell. Moving your data in stages is a smart way to avoid system overloads that could crash your systems after attempting too many transfers simultaneously. Monitor progress and stick to your planned timeline. To check out the complete migration steps, read this article on Tenant to Tenant Migration.

After migrating all of your content successfully into the new tenant platform, run thorough tests on newly-migrated applications so that everything runs smoothly without any issues. Test end-to-end functionality before training users on how to make use of the new platform. If you want to migrate OneDrive data also, check out Cross-Tenant OneDrive Migration.
