What to do

Upgrade all Service Fabric clusters running Windows Server 2019 to Windows Server 2025 before 31 Mar 2027 to remain in a supported state.
Perform the OS image upgrade by scaling the cluster node types. See Scale up a Service Fabric primary node type and Scale up a Service Fabric non-primary node type.
Some documentation references an upgrade from Windows Server 2019 to 2022. The same process applies to all supported Windows Server OS image upgrades, including Windows Server 2025.
