I have a SQL server 2012 on Windows Cluster 2008 R2 and need to upgrade . And need to do inplace upgrade.
And I know the node need to evict from the cluster first before upgrade.
After upgrade to Windows 2016 , Failover cluster manager is not able to open . 
how to solve it ??
I will need to reinstall the failover cluster on the upgraded server ..
Also how to add back the SQL Server service on to the cluster role ?? Coz I can't see Sql Server in other resources ..
