After upgrading my gateway from 8.0.12 to 8.0.15. I noticed that my jdbc directory now has the MS SQL jdbc driver jar that ships with ignition and also the MS SQL jdbc driver I had upgraded to when the gateway was 8.0.12.

Couple questions. How can you tell which jar file the gateway is currently using for the database driver? After upgrading the gateway do I need to make sure and reinstall the JDBC driver?

You’ll have to look at the `JDBCDRIVERS` table in the internal DB. The installer doesn’t touch the internal DB, so your SQL Server driver should still be pointing at the jar you configured.

I think we may need to look into how we’re handling that JDBC folder with the new installer, as dropping in missing JDBC jars may cause more confusion than benefit.
