Cross-tenant SharePoint migration can become complicated pretty quickly when an organization has dozens of sites, document libraries, lists, folders, and a large amount of historical content. I recently came across a migration requirement where the main concern was not simply moving files, but keeping the site structure organized while avoiding duplicate or previously migrated data.
One approach is to manually map source and destination sites and then move the required content selectively. This is particularly useful during mergers, acquisitions, tenant consolidation, or when a company is moving to a newly structured Microsoft 365 environment. If the goal is to migrate SharePoint to Office 365 (https://www.sysinfotools.com/blog/migrate-sharepoint-to-office-365/), it is also important to decide which content actually needs to be transferred instead of blindly moving everything.
For larger environments, I found the SysInfo SharePoint Migration Tool interesting because it provides site mapping, batch processing, filtering, and migration progress tracking within a graphical interface. The option to skip previously migrated files can also help when a migration is interrupted and needs to be resumed instead of starting from scratch.
Another practical consideration is authentication. Modern OAuth 2.0 authentication and Entra ID-based access are much more suitable for current Microsoft 365 environments than relying on older authentication methods. Having options for browser-based authentication or admin impersonation can make the setup more manageable for administrators working across tenants.
Filtering is another area that deserves attention before starting. File size, extensions, content type, and created or modified dates can be useful when only specific SharePoint content needs to move. This can significantly reduce unnecessary data transfer.
The Microsoft SharePoint migration tool approach is therefore worth evaluating based on the migration size, authentication requirements, site structure, and the type of content that needs to be preserved. I would recommend testing a representative set of sites first, checking the reports, and then moving toward the larger migration in batches.
