Apple recommends downloading the High Sierra OS from the Mac AppStore. It is recommended to download the High Sierra due to security and compatibility reasons. During installation, your Mac might restart many times. It will then perform some initial setup tasks in the background. Download Apple MacOS High Sierra for Mac to get a boost with new technologies in the latest Mac OS update coming fall 2017. MacOS Sierra (version 10.12) is the thirteenth major release of macOS (previously OS X), Apple Inc’s desktop and server operating system for Macintosh computers.

Anything from Apple's download servers is an update, and not a full installer for that version of the operating system. The only full upgrade installers are in the Mac App Store, and here is the link to How to upgrade to macOS High Sierra.
Before you leap from Yosemite, check the specific printer/scanner vendor driver sites to verify if either have High Sierra driver support. Also check with your third-party applications vendor sites that their applications remain compatible with High Sierra, and preferably, are 64-bit applications. Although the vendor sites are the last word on application support, you may find RoaringApps helpful too.
I would also recommend the following:
- Download and run the free Malwarebytes for Mac before any upgrade to see if any malware presently exists on your Mac, and if found, can be removed. Subscription for continued realtime features is purely optional.
- Boot into Yosemite Recovery (⌘-R) and run Disk Utility First Aid on your startup drive.
- Perform one last Time Machine backup before the upgrade.

macOS Big Sur takes the most advanced operating system in the world to a whole new level of power and beauty, making your apps look better than ever on an all-new interface. New widget features and the new widget gallery help you deliver more value to your users. Adding intelligence to your apps with machine learning is even simpler and more extensive with new tools, models, training capabilities, and APIs. You can create more powerful Mac versions of your iPad apps with Mac Catalyst. And you can now easily bring your extensions to Safari — and to the App Store.
All-new Interface
macOS Big Sur brings a new design that’s been finely tuned for the powerful features that make a Mac a Mac. Core features, such as the menu bar and Dock, take advantage of the large Mac display, with translucent backings and spacious pull-down menus. The new Control Center, designed just for Mac, provides quick access to controls while keeping the menu bar clutter-free. Notification Center puts recent notifications and powerful new widgets together in a single view for at-a-glance information as you work. And a streamlined new design for apps features full-height sidebars and integrated toolbar buttons.
Widgets
Easily build widgets using the WidgetKit framework and the new widget API for SwiftUI. Widgets now come in multiple sizes, and users can visit the new widget gallery to search, preview sizes, and add them to Notification Center to access important details at a glance.
Safari Extensions
With support for the popular WebExtension API, it’s even easier to bring powerful extensions to Safari. Xcode 12 even includes a porting tool to streamline the process.
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community.
Machine Learning
With macOS Big Sur, creating apps that leverage the power of machine learning is even easier and more extensive with additional tools in Core ML for model deployment, new models and training capabilities in Create ML, more APIs for vision and natural language, and improved resources for training on Mac and converting models to Core ML format.
Mac Catalyst
Create even more powerful Mac versions of your iPad apps. Apps built with Mac Catalyst now take on the new look of macOS Big Sur and help you better define the look and behavior of your apps. You can choose to turn off automatic scaling of iPad controls and layout, allowing you to precisely place every pixel on the screen. Provide full control of your app using just the keyboard, take advantage of the updated Photos picker, access more iOS frameworks, and more.
User privacy on the App Store.
Later this year, the Mac App Store will help users understand apps’ privacy practices. You’ll need to enter your privacy practice details into App Store Connect for display on your product page.
