While there are probably plenty of people who are torn about whether its worth it to buy a PS4 Pro, there are several reasons why gamers might want to purchase one including how wonderful games like Titanfall 2 can look on the new console. If worry about not transferring over your game saves is holding you back, don’t let it.
Once the transfer is done you can chose to set your PS4 Pro as the primary console. That is it! However note that if you have a lot of data that needs to be transferred, the best way is to leave the transfer overnight. In this way, you will most likely find everything done and completed while you are asleep.
