Our application is in 7.1.5 in VM based environment. We need to update it to Version 7.4 under app engine ( Containerization with Docker that generates dynamic nodes). What needs to be done. Will including 7.4 war files in Docker work? Or I need to take care of other things?
For Update or Upgrade, we have to follow the guidelines in "Appendix C — Optional: Generating and applying DDL" Correct? Because we will not be given write access by the DBA. Will it migrate our existing application rules too? If yes, what exactly is the difference between Update and Upgrade??
