I have been running Windows 2012 R2 cluster with SQL server 2014 instances. Below is the setup.
Stretched cluster.
abc.xyz.com - Cluster host-name.
2 Nodes at site 1.
2 Nodes at site 2.
All nodes are Windows Server 2012 R2. Can I drain roles and evict node one by one and do in-place upgrade directly to Windows Server 2019 ?
Thanks
