Error while Upgrading CMS to 7.1.10 using folder replace "Sequence contains more than one matching elemen"

Vote:
 

I have upgraded CMS to version 7.1.10 using folder replace method (modules, modulesrepository in VPP folder and modulesbin folder in site root).

Folder replace method was used as we didnt have internet access on our Intranet website.

This process completely worked on my ST machine, but show an error as below on UAT
