Assumptions

Assumptions…You want to upgrade your Private Cloud
infrastructure
![Page 7: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/7.jpg)
Assumptions…What you care about most is… users of your Private Cloud infrastructure do not notice that it is being upgraded
![Page 8: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/8.jpg)
Assumptions…Buying new hardware in order to upgrade.. will really slow down the process
![Page 9: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/9.jpg)
Assumptions…Just because you are upgrading software right now… does not mean that SLAs no longer apply
![Page 10: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/10.jpg)
Assumptions…Maintaining high-availability… throughout the upgrade process is important
![Page 11: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/11.jpg)
Assumptions…Guest operating systems are upgraded… with a different cadence / process to that of virtual infrastructure

Several storage topologies supported: SAN, JBOD, etc.
Scalability of the Scale-out File ServerSMB3 Continuously Available (CA) File handlesAdd nodes to scale

New Features Require OS Upgrade and…Upgrading the OS is difficultLarge scale and increased release cadence results in sticking with older versionsAdditional hardware/capacity required for OS Upgrade
Specific Requests…Don’t require new clusters to be createdDon’t require the cluster to be stoppedDon’t require any Hyper-V or Scale-out File Server down-time
Make it easy, make it “just work”

Back-up important data before Cluster OS Rolling UpdateBackup clusterBackup workload data
Check your uptime commitments and “Failover Capacity”Optionally add capacity to maintain (or increase) availability during upgrade
Two-node Scale-out File Server clusters will not be able to Failover while one node has been evicted
Some Operations will not be supported in Mixed-ModeProvisioning new storageChanging storage formats before Cluster OS Rolling Upgrade is complete
Storage Pool can be upgraded after Cluster OS Rolling Upgrade using Update-StoragePool cmdlet.

Introduced Cross Version Live MigrationGreat Feature But…
Only enabled migrations from Windows Server 2012 to Windows Server 2012 R2Private cloud upgrade required two clusters (2012 and 2012 R2 cluster)High availability gap during cross cluster migration
Cross Version Shared Nothing MigrationGreat feature but…
Same challenges with cross version live migrationRequired copying potentially large amounts of dataOften required additional storage

Cluster OS Rolling UpgradeFrequently Asked Questions

Frequently Asked Questions (FAQ)
(1) How long can clusters run in Mixed-OS Mode?
Between two and four weeks. Cluster OS Rolling Upgrade can be quick – it usually takes only a couple of hours - we will be providing guidance and documentation to customers that we will support a cluster running in mixed-os mode (WS.2012 R2 and WS.Threshold nodes) for between two weeks and four weeks. There are many improvements in v.Next clusters that customers will want to take advantage of as soon as possible.
(2) Will you have end-user documentation?Yes. TechNet documentation for Cluster OS Rolling Upgrade in v.Next Technical Preview has already been published. 75
![Page 76: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/76.jpg)
Frequently Asked Questions (FAQ)
(3) Will you back-port this feature to Windows Server 2012, or Windows Server 2008 R2, or Windows Server 2008?
No – at this time, we do not plan on back-porting this feature.
(4) Will you support “in-place upgrade” for the individual cluster node instead of “clean OS install?”
No – most customers have told us that they prefer a clean (fresh) install of Windows Server. 76
![Page 77: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/77.jpg)
Frequently Asked Questions (FAQ)
(5) Will you support Preview-to-RTM Cluster OS Rolling Ugrade?
No. Our mission is to smoothly transition customers from RTM release to v.Next RTM release. Customers should not take the Preview release into production.
(6) Does the Windows Server 2012 R2 cluster need to be fully patched before we can start with the Cluster OS Rolling Upgrade process?
Yes. The Windows Server 2012 R2 cluster must have all of the latest recommended patches installed prior to starting the Cluster OS Rolling Upgrade process. 77
![Page 78: Hyper-V System Center Components Scale-Out File Server Hyper-V Scale-Out File Server](https://reader037.vdocuments.site/reader037/viewer/2022110207/56649d825503460f94a67ade/html5/thumbnails/78.jpg)
Frequently Asked Questions (FAQ)
(7) Cluster Aware Updating (CAU) Work in Mixed-OS Mode?
Yes. CAU will continue to work while the cluster in running in Mixed-OS Mode, appropriately patching Windows Server 2012 R2 and Windows Server vNext nodes as needed. Please be aware that CAU uses node drain, and may take nodes out of the cluster during Cluster OS Rolling Upgrade – some customers turn CAU off while upgrading their clusters with the Cluster OS Rolling Upgrade process. (see Stop-CauRun PowerShell cmdlet)
(8) Can I run Update-ClusterFunctionalLevel while nodes are OFF or Paused?
No. All cluster nodes must be on (in active membership) for the Update-ClusterFunctionalLevel to work. 78
