Cloudsfer

Cloudsfer (developed by the highly respected migration experts at Tzunami) is an incredibly versatile, highly aggressive, and fiercely competitive cloud-to-cloud migration platform that fundamentally distinguishes itself by offering a staggering breadth of supported cloud connectors. While Mover focuses entirely on funneling people into Microsoft, Cloudsfer acts as a universal, agnostic hub for the entire cloud ecosystem. The core differentiator of Cloudsfer is its "Staggering Multi-Cloud Unification." It natively supports over 20 different cloud storage providers, including niche or specialized platforms that other tools ignore. A user can seamlessly migrate data from Alibaba Cloud, BIM 360, Jungle Disk, or WebDAV directly into Google Drive, SharePoint, or Amazon S3. It is the absolute Swiss Army knife for highly complex, multi-vendor cloud architectures. Furthermore, Cloudsfer offers highly advanced metadata handling and a fully managed service option (where their engineers execute the migration for you). It handles complex filtering (e.g., "Migrate all files from Dropbox to Google Drive, EXCEPT files older than 3 years or files larger than 1GB"). For organizations executing highly complex, cross-platform migrations between niche or massive cloud storage providers, Cloudsfer is incredibly potent.
