Windows Server 2019 Insider Preview Build 17639 released
In this month’s Patch Tuesday event, the first cumulative update for Windows 10 Version 1803 and multiple update rollups for Windows 7/8.1 was released. Microsoft also announced the new version of Windows Server 2019.
One of the many functions introduced this time is system upgrade, which allows to directly upgrade from the previous Windows Server to the new version while keeping related settings, functions, and applications. The upgrade path is as follows:
| CURRENTLY INSTALLED OPERATING SYSTEM | AVAILABLE UPGRADE VERSION & EDITION |
| Windows Server 2016 Standard | Windows Server 2019 Standard or Datacenter |
| Windows Server 2016 Datacenter | Windows Server 2019 Datacenter |
| Windows Server 2012 R2 Standard | Windows Server 2019 R2 Standard or Datacenter |
| Windows Server 2012 R2 Datacenter | Windows Server 2019 R2 Datacenter |
The main features in the new version are:
- Storage Migration Service
a new role included in Windows Server Standard and Datacenter editions. SMS is a job-based orchestration and proxy that:
- Allows administrators to inventory existing servers for their data, security, and network settings.
- Migrates that data, security, and network settings to a new, modern target by using the SMB protocol.
- Takes over the identity of the old server completely, while decommissioning the original source, in such a way that users and applications are unaffected and unaware that migration has taken place.
- Improvements to (Storage Replica) SR
