Hi Jason, I have done this in the past. (3x LSI 1068E - IBM BR10i).
Your pool has no tie with the hardware used to host it (including your HBA). You could change all your hardware, and still import your pool correctly. If you really want to be on the safe side; you can export your pool before the firmware change and then import when your satisfied the firmware change is complete.
