Upgrade the Primary Node
Complete these steps:
1. Disable hosting on the primary node and verify that all virtual hosts have moved to a backup
node.
2. Apply the upgrade.
3. Enable hosting on the primary node. By default, Virtual SQL Servers are set to NOFAILBACK
and will remain on the backup node. If you want a Virtual SQL Server to fail back to the primary
node, you will need to disable an instance associated with the Virtual SQL Server on the backup
node currently hosting the Virtual SQL Server. The Virtual SQL Server will then fall back to the
primary node.
