The TFS Migrator tool, which is used to migrate data from TFS to Azure DevOps (formerly known as Visual Studio Team Services or VSTS), is no longer available for download from the Microsoft website. The tool was retired in 2019 and Microsoft no longer supports it.
Instead of using TFS Migrator, Microsoft recommends using the Azure DevOps Database Import service to migrate data from TFS to Azure DevOps. This service provides a supported, scalable, and more efficient way to migrate your data.
Here is the link for the Azure DevOps Database Import service documentation:
https://docs.microsoft.com/en-us/azure/devops/migrate/tfs-azure-devops-migration-overview?view=azure...It is also recommended that you plan your migration and test the migration on a non-production environment before migrating your production data.
