I have installed Ubuntu on a small partition and its size is 60GB, and now I want to move it to a bigger partition.

I want my system to be at partition 6 without losing my data,
and if i can merge partition 5 and 6 at the same time.
knowing that partition 3 is for windows 10 , and also I don't wont to lose it.
