What will happen with the configuration once Insight membership expires

Hi

I have have a Wax620 and a wax610Y devices. Let's say I add them to Insight, put some configuration and use the devices until the Insight membership expires, at that point for XYZ reason I decide not to renew my membership, in this scenario I know I will have to continue managing my devices with the local  interface, but the question is: Will the configuration remain the same or will the devices lose the configuration they got from Insight?

Thank you
