We are upgrading to CCE 11.6 and the SQL Server will be 2014 SP2, however I have a server with SQL 2016 that I run other reporting from. Can CUIC use SQL Server 2016 as a valid data source?
I have not tried this but I would be pretty confident of it working. CUIC 11.6 supports TLS 1.2 and I bet the server that is hosting the SQL 2016 is only allowing TLS 1.2
