In the documentation for Splunk DB Connect v2.4.0, the only MS SQL JDBC driver mentioned seems to be the older 4.0 version: sqljdbc4.jar. In the documentation for Splunk DB Connect v3.1.0 the recommended MS SQL JDBC driver is version 4.2: sqljdbc42.jar.

Does anyone know if the more recent JDBC 4.2 driver works correctly with DB Connect 2.4.0?
I also notice that Microsoft don't seem to support JDBC 4.0 with JRE 1.8:
https://docs.microsoft.com/en-us/sql/connect/jdbc/system-requirements-for-the-jdbc-driver
Motivation: The migration process from 2.4.0 to 3.1.0 simply keeps the same driver, moving it to a new location it seems. This is understandable. I'd like to upgrade the JDBC drivers first, maybe X weeks before migrating the whole app so I don't have to include that in the migration (or back-track if something goes wrong).
