Yes, you have two different configurations: Content-Data and Content-Data-Configuration which are trying to serialize the same item (/sitecore/content/Data/Configuration). This is not supported and the solution is to remove this path from one of the configurations then reserialize. The path may not be referenced directly in both configurations – e.g. you could include the parent path with children in one of them and directly in the other one and that’s why it’s included twice. I hope this helps!

The trees Content-Data and Content-Data-Configuration both contained the global path /sitecore/content/Data/Configuration – overlapping trees are not allowed.

I am trying to install a package from production copy.
