Need suggestions on switching between mash & ferment settings

I have ONE Brewpi which i want to use for mashing (works great) & fermenting (works great as well). I need suggestions on how to change between these two in an easy way without lots of manual setup each time…

Thoughts:
Using two different Pi2 with pre configured settings or using two preconfigured SD cards.

Question:
How to get the settings pushed to the brewPi in an easy way after swithing Pi / SD card?

I think all settings are stored on the photon, so no use swapping SD or Rpi. It would be enough if the settings from the photon can be saved in a file. Then you just loaded the appropriate file in the photon.

And that would allow making a backup too in case the brewpi dies and is replaced.

Can you please help me, where I can find any information on how to config the brewpi for mashing?
I could not find anything to it!

I found it in this thread:
