Upgrade to High Sierra from Sierra

The earliest version of High Sierra I can find is 10.13.2. Can I upgrade directly from Sierra 10.12.6. If so do I use updater 10.13.2 or combo updater 10.13.2.

Thanks it turns out that an early copy from November 2017 of high Sierra installer had been automatically downloaded to my applications folder back then. Every time I tried one of the suggested links, including yours, instead of downloading the file it simply attempted to open the (unknown to me) 2017 installer file, and then reported that the file was damaged and couldn’t be used to install high Sierra. Once I discovered this old damaged installer and trashed it all the suggested links, including yours, became functional and now I have high Sierra installed and functioning. Thanks for the suggestions.
