We've been planning a SharePoint Online migration between Microsoft 365 tenants and realized that handling sites, document libraries, lists, files, permissions, and metadata manually can become overwhelming, especially for larger environments.
While researching, I came across the SysInfo Microsoft SharePoint Migration Tool. From what I've seen, it supports migrating SharePoint Online sites, document libraries, lists, folders, files, and metadata between Microsoft 365 tenants. It also mentions features like automatic site mapping, incremental migration, duplicate handling, selective migration filters, migration reports, and Microsoft Graph API with OAuth 2.0 authentication.
I'm curious if anyone here has actually used it in a production environment. How was the migration speed? Did it preserve metadata and permissions correctly? Were there any issues during large tenant-to-tenant migrations?
I'm looking for real-world experiences before deciding on a migration solution. Any feedback or recommendations would be appreciated.
