Create a new Changelog file (located in src/main/liquibase) (ex: src/main/liquibase/changelog-v1.0.0.xml). Add new Changesets in the Changelog file (no sub files as changelog will be fingerprinted and archived by Jenkins).
Use Maven:
mvn liquibase:update -Dliquibase.changeLogFile=src/main/liquibase/changelog-v2.0.0.xml
