Flexible instance resizing: Upgrade or downgrade your instance
The Resize tab, located on the instance page, provides you with the ability to upgrade or downgrade your instance by selecting a package from the available categories, which include Standard, Memory-Optimized, and CPU-Optimized.
If you opt for the CPU & RAM only package, you can upgrade or downgrade to/from any package.
However, if you choose the DISK, CPU & RAM option, you can only upgrade, as downgrading the disk can potentially lead to data corruption.
With the Resize tab, you can adjust your instance resources according to your requirements, providing scalability and customization options for your virtual machines.
