EKF2 vs EKF3 on fmuv2 Firmware Version

ArduCopter Copter 3.6

Is there any danger in running EKF3 on a pixhawk 1 flight controller running an fmuv2 firmware build? Will I have any sort of memory issues? I have been running EKF3 on a vehicle using the pixhawk cube running fmuv3 firmware, and I would like to run the same configuration on a vehicle using a pixhawk 1 with fmuv2 build.

Am I asking for trouble?

Any help or advice would be greatly appreciated.

Thanks,
James

you must consider the pixhawk cube is more recent rather pixhawk., You can try set the EKF 3 on you pixhawk 1, but test the behavior of the drone before a complete a flight
