Hi DouglasTanner-4383,
Is it possible to failover the 2016 SQL instances, on nodes 2 & 3 to node 1, which is now running SQL 2019?
Do you want to upgrade the SQL failover cluster instance in-place from 2016 to 2019? If I misunderstood, please let me know.
If so, you can go to the Failover Cluster Manager, in the right menu, select “Roles” -> right-click on the cluster and select “Move” -> “Select Node”.
Then you can select one of the passive nodes you want to move.
In addition, to upgrade a SQL Server failover cluster instance, please use SQL Server setup to upgrade each node participating in the failover cluster instance, one at a time, starting with the passive nodes.
Please refer to Upgrade a failover cluster instance and this similar thread which might be helpful.
Best Regards,
Amelia
