Our organization is planning to move its Microsoft 365 environment to a new tenant, and one of the biggest concerns is transferring employee OneDrive files without affecting their existing work. Employees store project documents, reports, spreadsheets, presentations, and other business information in OneDrive, so maintaining the original folder structure and ensuring files reach the correct destination accounts is important.

I would like to understand how administrators generally approach this process. Is it better to migrate each user's OneDrive separately or handle multiple accounts in batches? Another concern is how to manage shared files, permissions, and destination user mapping when the source and target tenants have different account structures.

In my opinion, preparing an inventory of OneDrive accounts, checking storage requirements, and creating destination users before migration can help avoid unnecessary complications. It is also important to verify the transferred files and their folder structures before users start working in the new environment. For larger organizations, testing with a few accounts first can help identify potential issues.

A dedicated tenant to tenant migration tool can make this type of project easier to organize. I came across the SysInfo Microsoft 365 Tenant to Tenant Migration, which supports transferring OneDrive data along with Exchange mailboxes, SharePoint content, and Teams data between Microsoft 365 tenants.

The office 365 tenant to tenant migration tool provides options such as user mapping, incremental migration, duplicate detection, and selective data transfer. These capabilities can be useful when administrators need to move information for multiple employees without repeatedly transferring the same content.

The sysinfo tenant to tenant migration tool is worth evaluating when planning a multi-workload Microsoft 365 migration.
