We have 2 Hyperv Servers and a SAN. When they were configured, High Availability wasn’t on the horizon. But it is now.
Can I convert the current servers in place to use Failover Clustering?
Or
Would I have to create a cluster with different hardware, migrate the current VMs over to them, and then bring in the older servers?

I don’t think you can do it in place but it’s fairly straightforward. Once once you have the servers in a cluster simply move them in and make them highly available. Basically:
- Export/backup your VMs
- Add the Failover Clustering feature on both hosts
- Configure networking (probably the biggest pain)
- Carve out storage on your SAN for the clustered shared volume
- Since you only have two hosts you’ll also need a little room on your SAN for a Witness Disk
- Start the Failover Cluster Manager and Validate the cluster
- Then “Create a Cluster”
- Move the Vms to the clustered shared volume and make them highly available.
