Comparison matrix
The following comparison matrix shows basic functionality of different tools that can be used for migration of unstructured data.
Tip
Azure File Sync can be utilized for migrating data to Azure Files, even if you don't intend to use a hybrid solution for on-premises caching or syncing. This migration process is efficient and causes no downtime. To use Azure File Sync as a migration tool, simply deploy it and, after the migration is finished, remove the server endpoint. Ideally Azure File Sync would be used long-term, while Storage Mover and AzCopy are intended for migration focused activities.
