Pormoting DDL changes from one to another Database

Team, I have made changes(adding a new table, and altering a column) in dev database. Now how to push these changes to prod environment. generateChangeLog will always generate full DDL. I want promote just new changes not the entire database.



Can you please clarify a little more ? Do you have Liquibase set up to run on production database or not yet?
Have you made changes in dev environment manually. You can run a diff command to get the differences or diffchangeLog to get SQL script that you can use.

Let me know if you run into any issues.
