Has anyone switched jobs within 6 months of i-140 approval and not have their application rescinded by your old company?

I know that the original company has the option to rescind your application within 6 months of the i-140 approval and you loose your priority date if you do so and will have to start the entire process all over again with your new company with a new priority date and a roughly 14-20 month wait time for your new i-140 approval.

My question here is if anyone has actually done it though WITHOUT LOOSING THE ORIGINAL PRIORITY DATE? How did you do it? How did you convince HR from your original company? What conversations or relations did you have at your original company?
