Spencer soaking the compot is the way to go as it makes it easier to untangle the roots. It's always hard not to damage some roots
Here's a pic of a compot that I recently repotted.
The larger plants in this compot went into their own individual pots.
The smaller plants went back into a couple of compots. The larger plants end up shading the smaller plants and therefore they don't grow as fast.
Putting the babies back in compots is a good idea. They will soon have a growth spurt with the additional light and more room to grow.
The larger plants in this compot had LS of 7" or more and the babies 3-5" which could have gone into their own pots but compots keep them more evenly moist which adds in their developement.
Hope this helps!!
