There are no old software versions to remove. An iOS update replaces the previous operating system. And app updates also over-write the current app, replacing it with the new one. There is no accumulation of older copies of software in your storage space. The only thing there ever is on the device is the current version of iOS and apps - the installers over-write the installation with new, and then delete the installer itself and any temp files from the installation process.
