Transplanting Help/Advice

My plant is almost 2 months old and for the remainder of this grow I want it to be rooted into the ground instead of this pot it is in. The pot is about 2-3 gallons and I was wondering what the best way to transplant it is. I.E. do i remove all the soil or try to pull it out of the pot at an angle. Thanks for any advice or help that is given.
My plant is below

I always remove the soil around the plant and try to keep the roots intact and transplant to another pot with a little dirt in it.

Okay and Im going to be putting it into a hole maybe twice as deep as the plant shuld i fill the bottom of the whole with soil then put the rootball on top of the loose soil and then gently pack in the rest of it?

I would transplant tree style then. Just set your root ball in the hole you have then just fill around with soil. I'm sorry I was thinking inside transplant from pot to pot.

Yes it should work fine, just make sure the hole is nice and big. add some soil to the hole, put the plant in then fill in around it.
