Hi, I am a novice user of myRIO/Lavbiew.
So far I am using the default FPGA personality, but recently I was given a bitfile ending with the extension .lvbitx”. I needed some of additional functionality which the new bitfile will provide me, but I'm not so sure I'll stick with it and there's a chance I need to roll back to the default FPGA personality.
Installing seems pretty straight forward with Ni MAX. I just browse to remote_system>myRIO>device_interfaces>myRIO_FPGA and click on update firmware and it will allow me to browse to the location where I stored the given bitfile.
My concern is that if update FPGA firmware to this bitfile, will I be able to roll back to the old default FPGA firmware/bitfile if I wanted to? I have no idea where current bitfile is stored. Do I need to manually restore it or will it come back once I click on “erase firmware”? There is a high chance that I need to use back the original default personality.

I expect that clicking "Erase Firmware" will not restore the previous firmware.
There is Replication and Deployment utility, maybe making an image will help:
