Author: Yoann Rodière <yoann(a)hibernate.org&gt; Date: 2023-03-02 (Thu, 02 Mar 2023) Changed paths: M migration-guide.adoc Log Message: ----------- Fix recommendation in migration guide for duration mapping backwards-compatibility Quoting: "5.x used the type code `Types.BIGINT`". So, in order to retain backwards-compatibility, one needs to set the JDBC type to `BIGINT`, not to `NUMERIC`. Tested locally on a schema created with 5.x by starting an application using 6.x: with `NUMERIC`, schema validation fails; with `BIGINT` it does not.
