Happy to help if you do decide to switch. This covers most of the basic differences: https://cljdoc.org/d/seancorfield/next.jdbc/1.0.462/doc/migration-from-clojure-java-jdbc
But clojure.java.jdbc is rock solid. We’ve used it in production for nine years and I’ve been keeping it maintained all that time. I didn’t want to make breaking changes to it, at this point, so next.jdbc is the “1.0” that I never quite got to with c.j.j.
