In 1802 TP, when you create a upgrade Task Sequence, now there will be additional groups created that is based on recommendations what Microsoft and others have seen done in the field. These groups are just recommendations and the actual tasks/scripts to do the checks, installs, etc. will need to be done by you. Several example scripts are out on the next that can help you get started.
Some examples and additional recommendations are available here https://docs.microsoft.com/en-us/sccm/core/get-started/capabilities-in-technical-preview-1802
