Request for assistance on Kegberry data recovery

My Kegberry died last week. I was only using it for the kegbot server functionality since I already have a Nexus 7 configured with my controllers. The RPi will not boot, but I can mount the root filesystem from the SD card on other Linux systems in my environment. If I rebuild my Kegberry with another SD card, is there any chance of being able to copy the data over and pick up where I left off? Unfortunately the last backup I have is several months old.

Any assistance anyone can give is greatly appreciated!
