Oracle Database Administration from Zero to Hero - Practice - Upgrading Oracle Grid Infrastructure

This video tutorial covers the process of upgrading Oracle Grid Infrastructure from release 19C to 21C. It begins with an overview of the upgrade process, followed by preparation steps such as downloading necessary software and creating a snapshot of the virtual machine. The tutorial then guides viewers through executing the upgrade, including running verification scripts and addressing any issues. Post-upgrade actions are discussed, such as updating environment variables and detaching the old grid home. The video concludes with a summary of the process and emphasizes the importance of having matching release numbers for both the database and grid infrastructure.
