Change the component layout

When you upgrade a Core, SA attempts to identify the component layout of your existing core. If SA cannot determine your core’s component layout (typical or custom), you will be prompted to specify the component layout mode used during the core’s installation. The layout must be the same as you chose when you installed the core. If you choose the incorrect layout and SA cannot determine the correct layout, the upgrade can result in an inoperable system due to mismatched component layout.

In SA cores with distributed core components, all components must be of the same SA version. Mixed SA version core components are not supported.
