Not sure this is something which people will know on here are not.
We currently have a BI setup where we have Integration services on one SQL instance and the data warehouse database on a separate SQL Instance.
My question is, as no users physically connect to the Integration services SQL instance and it is purely used to execute package from the integrations service catalog via SQL agent, do we need to License every user i.e. Cal's for that SQL instance.
Basically i'm wanting to know if I could utilize SQL 2016 for an integration services instance and use features like Json manipulation etc and then load this data into the 2014 version instance...but what level of licensing will I need?
