2 things will happenz the rootball will have filled the pot enough, when you pull it out slightly dry it should come out in a nice solid football. If you manage to get it out and in to bigger pot with minimal fuss.
Small chance it will just go everywhere and set back growth a good week at least from the blowout.
Look to invest in airpots in future, beauty of them is you can upsize without even taking the pot off if you so choose. Comes with screws too which makes getting it out the pot a breeze. Wish you 🤞
