[Snapshot Pro] "Snapshot Pro" guideline

Dear sir,

I'd like to duplicate a page or a whole site with "Snapshot Pro". Which document should I refer to?

Case 1: pages duplicate of multisite

source page:
https://i98.tw/prestige/music-festival/
https://i98.tw/prestige/cruise/

target page/site:
https://marketings.wpmudev.host/music-festival/
https://marketings.wpmudev.host/cruise/

Case 2: site duplicate of multisite

source site:
https://i98.tw/skyrestaurant/

target site:
https://marketings.wpmudev.host/skyrestaurant/

Please advice. Many thanks in advance.

Cheers,
Sky
