Thank you for your response... I have this in my notes now, there are some machines left that I would like to uninstall the old and go with the new, so this will be an easier way than manual changing... thanks so much
Create the package in the following way:
1) Admin > Install Packages > Settings
2) Create a new setting which has the option of "Remove all previous logs, policies and reset the client server communication"
3) Use this setting while exporting the package.
4) Push with clientremote.exe or migration and deployment wizard
4) This will uninstall the existing clients, Reinstall them with the new configuration set.
