Windows Server Storage Migration Service

The Storage Migration Service was created to migrate servers and their data without re-configuring applications or users.

  • Migrates unstructured data from anywhere into Azure & modern Windows Servers
  • It’s fast, consistent, and scalable
  • It takes care of complexity
  • It provides an easily-learned graphical workflow

Windows Server 2019 and the Storage Migration Service are not supported in production environments!

This first version copies over SMB (any version). Targets like Azure File Sync servers, IaaS VMs running in Azure or MAS, or traditional on-prem hardware and VMs are all valid targets.

The feature consists of an orchestrator service and one or more proxy services deployed. Proxies add functionality and performance to the migration process, while the orchestrator manages the migration and stores all results in a database.

Storage Migration Service operates in three distinct phases:

  1. Inventory – an administrator selects nodes to migrate and the Storage Migration Service orchestrator node interrogates their storage, networking, security, SMB share settings, and data to migrate
  2. Transfer – the administrator creates pairings of source and destinations from that inventory list, then decides what data to transfer and performs one more or transfers
  3. Cutover – (not yet available) – the administrator assigns the source networks to the destinations and the new servers take over the identity of the old servers. The old servers enter a maintenance state where they are unavailable to users and applications for later decommissioning, while the new servers use the subsumed identities to carry on all duties.
