Have you handled deployments to higher environments? If yes, how were deployments managed in your project?

Yes, I have deployed to higher environments.

In our project, I have handled deployments to QA and Pre-Production environments, mainly for bug fixes and enhancements.

1. For ticket-based or selective bug-fix deployments, we followed Compare & Deploy to move only the required objects.
2. For full application or major release deployments, we used package-based deployment to ensure all dependent objects were deployed together in a controlled manner.
