OS X Mountain Lion (version 10.8) is the ninth major release of macOS, Apple Inc.' S desktop and server operating system for Macintosh computers. OS X Mountain Lion was released on July 25, 2012 for purchase and download through Apple's Mac App Store, as part of a switch to releasing OS X versions online and every year, rather than every two years or so.
Mac operating system’s twelfth major version is the El Capitan Installer (version 10.11). All the Mac computers which don’t have the privilege to upgrade to MacOS High Sierra or the computers that need to upgrade to El Capitan first, can download this twelfth version on the computer. This is the very last version of the Mac operating system which comes under the name OS X. And it is named as ‘El Capitan’ after the formation of a rock in the Yosemite National Park. El Capitan Installer is the post version to the Yosemite, and it was built by adding up more improvements to the Yosemite. In this version of the Mac operating system, the Apple Inc. has focused on the performance, stability, and security of the computer. Anyone who is interested can download it on the Mac PC.
OS X Mavericks (version 10.9) is the tenth major release of macOS, Apple Inc.' S desktop and server operating system for Macintosh computers. OS X Mavericks was announced on June 10, 2013, at WWDC 2013, and was released on October 22, 2013 worldwide. If you're using OS X El Capitan v10.11.5 or later and your App Store preferences or Software Update preferences are set to download new updates when available, macOS Big Sur will download conveniently in the background, making it even easier to upgrade.

Important! It is very important to backup your important data on the Mac PC to an external storage device because it will help you to avoid the data loss issues. If any case, you forgot to backup the data, your data may be lost while executing the El Capitan Installer update. So make sure you make a backup of the device data.
This is the easiest method for the clean install. Here, you can install the OS X El Capitan Installer onto an empty volume, or you can use a storage space that has the content which no longer needed and don’t mind removing. What it matters here is that you don’t use the current startup volume as the destination here. What makes this method easier is the fact that it is possible to perform this clean install while booted from the current startup drive. You don’t need a special, custom-made startup environment for the empty volume clean install. All you have to do is, start up the installer and go.
This is the most common method of the two. Usually, the clean install process deletes the contents of the destination drive. Therefore, if you choose the startup drive method to perform the clean install of El Capitan Installer, you have to follow some extra steps as well.

El Capitan Installer is only available in the Mac App Store. So you can only download it from the App Store. By the way, having a USB installer to perform the El Capitan is a good idea. Because having a copy of the OS version in a separate device ensures that you always have a backup plan to install it or re-install it on the PC. When you have the USB installer with the El Capitan Installer in it, you no longer need the internet connection or the access to the Mac App Store to perform the upgrade.

This is only available for the OS versions of Lion (OS X 10.7) and above.
You can either use the default method to upgrade install or clean install methods to get El Capitan Installer but, without any doubt, Clean Install is the best method to upgrade your Mac OS. I hope all the above facts prove that.
Simply, take a backup by using the Time Machine.
