How to handle vendor change when replacing a package

Hello List, We are trying to replace a package in our product that provides the same functionality. We have made changes to our package as documented at - https://en.opensuse.org/openSUSE:Upgrade_dependencies_explanation - but when "zypper patch" command is run, we are receiving a vendor conflict. If we run "zypper patch --allow-vendor-change" then the package dependencies are handled correctly. Both the vendor names are set to be equivalent. Hence my question is, how can we handle the vendor conflict when replacing a package? Any insights here would be greatly appreciated. Regards, Srinidhi.
