I am currently preparing for an upgrade of our existing Progress database from version 11.7 to the latest version 12.8. As this will be my first time performing a database upgrade in this environment, I would greatly appreciate a detailed and validated step-by-step procedure.
Here is a brief overview of the current application architecture:
- The frontend is built using Java and Angular.
- The backend logic and database are both implemented using Progress.
- The application communicates with the database using RESTful web services.
- Both Tomcat and HTTPD (Apache) services are actively running and are integral to the current system setup.
