Another feature included in Windows Server Standard and Datacenter editions is a new job-based orchestration and proxy called, “Storage Migration Service (SMS)” that provides “orchestrated workflow with a Honolulu-based graphical management system, allowing scalable migrations of many servers simultaneously to new targets running on premises or in Azure,” Microsoft wrote.
SMS’ intutive GUI backed by PowerShell automation handles common problems and subtleties of a migration, including in-use files, share settings, security settings, network addresses and names, local security principals, encrypted data, and more.

Storage Replica (SR) enables synchronous and asynchronous block replication of volumes between servers or clusters for disaster recovery. Also, using it you can create stretch failover clusters that span two sites, with all nodes staying in sync.
Additionally, following improvments to SR will be available in preview soon after build 17639:
- Log v1.1 lead to far better replication throughput and latency, especially on all-flash arrays and Storage Spaces Direct (S2D) clusters that replicate between each other. Just upgrade all servers participating in replication to Server 2019.
- Test Failover let you now mount a writable snapshot of replicated destination storage. Make sure to have an unused volume and temporarily mount a snapshot of replicated storage for testing or backup purposes.
SR will soon available on Server 2019 Standard Edition as well as on Datacenter Edition with following limitations on Standard Edition:
SR replicates a single volume (instead of an unlimited number of volumes).
- Volumes can have one partnership (instead of an unlimited number of partners).
- Volumes can have a size of up to 2 TB (instead of an unlimited size).
Starting with this build and all future pre-release builds are now require activation keys during the set up process. Following keys can be use for “unlimited” activations:
