Update Configuration via Dude

Dear All,

I have 5-6 routerboards with exactly the same configuration in my network .
I have also a test routerboard that i test the new settings

What i want is from the time i know the settings are correct on the test server to take a full backup of the system and then using the dude to select all routers and upload the configuration to them and restore the configuration on all these routers .

Any idea ??
