About Adding New Storage Servers to an Existing Rack

Additional patching considerations include the Grid Infrastructure and database home releases and bundle patch updates. If the software installation applies new patches, then Oracle recommends changing the existing servers so the new servers inherit the releases as part of the extension procedure. This way, the number of servers that require patches is lower. Apply any patches to the existing servers in advance, so that they are at the desired level when the extension work is scheduled, thereby reducing the amount of work required by the extension.
