I’m looking into ways to reduce risks before moving SharePoint content between Microsoft 365 tenants. From what I’ve learned, the biggest mistake would be treating the migration as a simple file-copying task. A SharePoint environment can include document libraries, folders, permissions, version history, lists, pages, custom properties, workflows, and user mappings, so each part needs to be considered before the migration starts.
I would begin by auditing the source tenant and identifying which sites are active, which libraries contain large amounts of data, and which permissions or configurations are unique. The destination tenant should have enough storage, properly configured SharePoint services, and the required user accounts. Creating a source-to-target mapping in advance also seems important because users and groups may not have identical identities in the new tenant.
For a small number of files, downloading and uploading them may be sufficient. However, that approach can cause problems when an organization needs to migrate SharePoint site to another tenant while retaining metadata, version history, permissions, and the original structure. Manually recreating these elements could also increase the possibility of human errors.
The native PowerShell method is another option, but it requires technical expertise and several preparation steps, including tenant relationships, authorization, and identity mapping. There are also limitations that administrators need to consider before selecting this approach for a large environment.
I’ve also been exploring the SysInfo Microsoft SharePoint Migration Tool because it provides features such as custom mapping, advanced filters, incremental migration, de-duplication, batch processing, and progress reporting. A staged migration could make it easier to test the process with a smaller group before moving the remaining sites.
For me, the most important part of SharePoint Tenant to Tenant Migration would be validating the destination after the transfer. Checking files alone isn’t enough; permissions, versions, metadata, and site functionality should also be reviewed.
For those who have completed a SharePoint tenant migration, what risk caused the most trouble in your project? Was it permissions, data volume, identity mapping, workflows, or something else that you wish you had planned for earlier?
