Cloner Staging and Production->Staging->Production Content

Hello. I am looking into using Cloner for staging and have a probably (hopefully) really simple logistical scenario and question:

Let's say I install Cloner and initiate a one-click staging of one of the sites in my multi-site. During the development (hypothetically 4 days) on the staging copy, content is added to the production site from which the staging copy was cloned.

When I am ready to apply the changes to the production site, what is the best way to make sure the 4 days of new content remains intact and the design/development changes take effect?
