Step-by-step explanation:
The Oracle recommended way to perform a migration from a development site to a QA site is to open the Migration Center in the development site, log into the QA site through the Migration Center section, select the components that you want to migrate, and then start the migration process.
This is to ensure a structured approach where the exported components from the development environment can be tracked and imported properly into the QA environment, enabling a clean handover of assets. It's essential to thoroughly test the migrated components in the QA environment to ensure they function as expected before moving them to the production environment.
