After creating a staging site, there are many options you can do other than pushing it back to the live site. In this article, we will explain the difference between the actions “Update” and “Reset”:
The update action will copy all the data from the live site to the staging site. It will not delete anything from the staging site, but it will update it instead, i.e., it will add any new database table or files to the staging site and update those existing ones.
The reset action will delete everything on the staging site and starts copying the data again from the live site.
So, it’s as if you deleted the staging site then created a new one but with the advantage of keeping all the settings with which you made the staging site the first time (external database credentials, excluded tables and files, and all other settings).
