Upgrading Discovery Appliance to new hardware

[#1]

I'm upgrading my old ND-2200 Discovery appliance on my grid to a new ND-2205. My question is if I take down the old one and bring up the new one on the same IP as we have done several times during this HW refresh cycle we are in, will I lose anything that stored locally on the old appliance? Is there some backup that can be done similar to the Reporting appliance if so?

Thank you
