Upgrading Server 2012 R2 to Server 2016 and Storage Spaces

Server 2016 has enhanced and added new features to Storage Spaces. Most notably is the introduction of Storage Spaces Direct, Storage Replica, and Storage QoS. This post explores upgrading a physical Server 2012 R2 that uses mirrored tiered storage space.

After installing Server 2016 (Desktop Experience), and choosing to keep ‘nothing’


In Server Manager, File and Storage Services\Volumes\Storage Pools, we see the old Storage Pool from the prior installation of Server 2012 R2


To recover the Storage Pool, its virtual disks, and all data follow these steps:

  1. Set Read-Write access server2016-19
  2. Upgrade the Storage Pool Version server2016-18Note that this step is irreversible
  3.  Right click on each virtual disk and attach it server2016-21
  4. Finally, in Disk Management, right click on each virtual disk and online it

The virtual disks retain the drive letters and volume labels assigned to them in the old 2012 R2 server. All data is intact.
