Can Dapps change what coin they are using?

[rob31]

Hello, say that one of these ICO's that are using erc20 tokens has a good business and does well. Later a coin comes out that is much better than using erc20. Can this company then change all over to some new token or are they stuck using the erc20 even if it is outdated? Thanks.

They can always make New coin from their token i guess, when new coin created with full nodes and all every token holder will receive same amount 1:1 new coin and make old token untradable or they can burn old token. Im not quite understand though so maybe next poster will give more explanation about it
