I have a 5 years old subfolder site
example.com/us and I have nothing in the root site
example.com. Now I want to setup a multisite in the root site to create a network, then I want to add the existing subfolder site
example.com/us to the network, would it be a problem? Do I have to do some extra work for that to work?
I've tried that in the localhost and it worked fine, but I want to be sure before moving to the Live setup.
I don't want to harm my site on Google, neither do I want to lose my link building. This website has thousands of visitors daily from Google, and I don't want to lose all that.
