At the moment my external storage is on a normal ps4 console with the version 6.00 beta system software. If I was to get a PS4 pro by the end of next week which is now on version 5.54 of the system software will my external storage work on the one with 5.54 or will I have to format the external drive ? is there any way around not formatting the external drive ? I notice in the system software update option it gives me a choice of version 5.56 & version 6.00 beta so is it possible for me to get the beta 6.00 re downloaded onto a pro as long as it is logged into with the same account so I don't have to format the external storage? can someone check/test this for me please ?
