Sured you can replant it now. Be sure to take the whole root ball with it.
It may sulk a day or two but should be fine.

I'm gonna take a shot here and say probably not.

If its too small already,

it won't get better by doing nothing.

I read an article recently that reccomended watering the plant first, well OK, that person should know more than I but that is not my experience.

I find that easy extraction is better done a little on the dry side and then flood it once transplanted.

If its too badly root bound, you might VERY gently lossen the twines around but be careful. For woody plants this is generaly a must but maters ???

If it wilts and STAYS wilted for two days straight, try removing one third to one half of what is wilted. The plant won't have to work so hard trying to keep something alive that it probably can't. If it wilts but that wilted part comes back, it will more than likely be OK.

I don't fertilize transplants till they show me they can handle it, other folks might feel differently. I do give them very good, loose soil and don't make em work too hard for water, for a while.

It all kinda depends on how root bound it is, how large and mature the plant is and this part is more art than science.

Best of luck

Go for it. Better now then have a sick plant throughout the season. Carfeully done and you can be successful!

get a 20" Pot, some Miracle Grow potting soil NOT garden soil, and transfer the whole plant into the new pot.

Tomato plants can be repotted any time, as long as your don't disturb the soil around the roots very much. Good idea to replant an inch or so deeper than they are now too, and use lots of half-strength Miracle Grow solution.
I just transplanted a three foot mater plant the other day....did not wilt at all.
