Sure!

Sink the old pot into the new one and fill in around it with moist, not wet, soil.
It's best if the soil is already ferted for bloom of course, but not too much at first.
You want the roots to go hunting, and multiply, then feed.

Gently lift the old pot out, invert it, tap it on the edge of something to jar the root-ball loose, and catch it.
Might need some help with biguns.

Set the shaped rootball gently in the hole you made, and she won't notice that she's been transplanted until she feels the extra toe-room.

From watching my DWC grows I found that Cannabis can, and does, grow lots of roots in the first 6 weeks of flower.
