Flush the pot with room temperature nonchlorinated water to expose roots gently release any tangles, dust roots with mycorhizzae and transfer to new pot.
I wouldn’t worry for a second about scooping one out of each of those pots. It’s hard to kill a weed. You may stall them for a few days while they repair the roots. I’d take as much root/soil as I could though. Then refill the hole with soil.
i do it over my soil bin or a wheelbarrow with soil, place one hand on top of soil, invert, shake, tap, lay on side in soil bin, ease’er out kinda at an angle. use your fingers or a chopstick to separate them, but fwiw, landscapers use a pruning saw on roots and so have i.
Sometimes I get lazy in my aerocloner and roots get all tangled and I just rip them apart and try and spray/rinse away any remaining ripped roots still clinging.
I ran into this problem a week ago, I just cut straight down the middle with a knife, split the dirt/plants into 2 pieces than finished the transplants. Worked very well id say.
