Unhappy [Q] Galaxy Mega 6.3 move to SD card information required

Hi
Have a quick question to ask and would really appreciate a good answer to it..
My Galaxy Mega 6.3 GT-19200 with v.4.2.2 having low internal memory card makes me very limited to use good games as you know its by default installed on the phone memory not the external memory as also DON'T have the move on SD card option on my phone
My Question is
... can i root safely and by that move my apps and large games to SD card and do you have any other suggestions ??

details would be much appreciated THANK YOU
