Replace Fridge, keep history and reset sensor for new one

Dear everyone,
I need a little help about the following topic: I am measuring the energy consumption of my current fridge with a shelly plug (integrated via the shelly integration), which is also shown in the energy dashboard.
I just ordered a new fridge and I want to keep the consumption data of the old one in my energy dashboard (eg as Fridge_old). At the same time, I want to reset the consumption data of my shelly plug to use it with the new fridge.
I thought I could rename the entity of my shelly device to *_old, but when I reset it to 0, all my data should be gone. Can anyone help me find a way to realize the scenario above?

Thanks a lot!
Lurchi
