The five positions are NOT 5 scales, just 5 ways to play the same scale.
Getting from box one to box two, I usually slide up 2 frets on the third string.
If you really want to get all the boxes involved,
I'd suggest you look into Griff's 3+2 Pattern https://www.youtube.com/watch?v=kZGelTM01h4
and his 2+3 pattern https://www.youtube.com/watch?v=Y8aGGbEj81k
