Hi,

Metronic 5 and Metronic 8 are 2 different themes due to major changes between used core plugins and Bootstrap library itself. So you will need to reintegrate the new UI based on Metronic 8 from scrarch. There is no automated way is possible since everyone uses the theme differently and there is no known pattern for automated updates for HTML templates.
