Pretty late for that tree, even though crabs are very tough, for zone 10.
The first thing to ask oneself when contemplating a repot is, “ Does the media percolate?”
Having lots of roots is not a consideration for repotting unless the rootball does not allow water to flow through. (Looks ok from the photos, but clear the screen areas, plunk the tree back in the pot and check.). btw from experience crabs push long roots very fast.
If the rootball does percolate leave the tree in the pot for the growing season. Repot next year.
If it’s just ok, take our up a handy dandy 3/16” long drill bit, even 1/4” might be ok for a crab, and your favorite drill. Then drill multiple 6-10 holes in the top and bottom of the rootball. Repot next year.
While the year goes by, gather together all the materials you’ll need for the repot next year.
cheers
