This is a conceptual question. Is it possible to somehow update an existing ERC-721 Token's
uri, after the NFT was already minted?
For instance, I minted an NFT where the asset location was
AWS S3. Later, I wanted to update it to
IPFS. Would this be possible for an already-minted NFT? Or, given how the blockchain is immutable, what I'm asking is conceptually impossible?
Please provide an illustrative example. Thanks.
