I don't do that & I found that the soil caves in anyway. I just fill the new pot up a little to create a bed of soil, sit the plant into the new pot, surround it with soil, and water it lightly.Honestly... Watching experienced people on YouTube has helped me out a lot... Do a YouTube search for transplanting plants to get a visual tutorial on how people do it... It's really easy.A good tip to repotting is before removing them from the pots, use the pot as a form to create the exact shape and size hole in the soil of the new pot.In other words fill the new pot half up with your new soil and sit the old pot on top, then put soil round the outside of the old pot and firm it in.Then when you remove the old pot with a little twisting, you are left with a hole which is exactly the same shape and size as the old pot.Do as Mr Sunshine says with the pot upside down and if it doesn't come out easily you can give it a gentle shake up and down.
It usually caves in if you just pull the pot out without twisting, but if you twist you pot as you pull it out you will find it stays put.To be honest I don't employ this method either however some people do find to be a helpful tip as it gives a good indication of how much soil is required round the out side of the pot, and allows for adjustments to be easily made so that you dont end up running out of soil for the last pot if your working with a limited supply of soil.Im sure youtube has many great videos on how to grow, and it is a good place for new growers to start. I have been growing since 1985 and I am happy with the way I do things, maybe sometime I may try my hand at hydroponics and I will probably be watching some videos when the time comes, but for the moment soil is good enough for me.I don't do that & I found that the soil caves in anyway.

lol sorry i didnt notice someone had already said my tip lol what baxter saidA good tip to repotting is before removing them from the pots, use the pot as a form to create the exact shape and size hole in the soil of the new pot.
In other words fill the new pot half up with your new soil and sit the old pot on top, then put soil round the outside of the old pot and firm it in.
Then when you remove the old pot with a little twisting, you are left with a hole which is exactly the same shape and size as the old pot.
