Have you created a clone and Time Machine backup?
Are you sure you really want to upgrade to a .0 update that makes major changes to the file system?
Have you checked to see if your apps will work in High Sierra.
Apple announced at WWDC that the company will start to phase out support for 32-bit software in macOS. In January 2018 (High Sierra will be released months before that), new apps submitted by developers to the App Store must be 64-bit apps. Also, all apps and app updates must be 64-bit by June 2018. Eventually, 32-bit support will no longer exist in macOS, probably in a version after High Sierra.
