Abstract
An apparatus in one embodiment is configured to extract a set of components utilized in a first version of a storage controller operating system (OS) to a designated partition of a storage system on which the first version of the storage controller OS is to be installed, and to identify changes to be applied for installing the first version of the storage controller OS by comparing content of the extracted set of components utilized in the first version of the storage controller OS with content of components utilized in a second version of the storage controller OS that is currently installed. The apparatus is also configured to apply, utilizing at least one rule corresponding to at least one component utilized in the first version of the storage controller OS, at least one of the identified changes to upgrade to the first version of the storage controller OS.
