How to Upgrade from ERC-721 to ERC721A in a Web3 Project, I have only JSON ABI Files?

[abdulrahmanRadan]

I am working on improving a Web3 platform that allows users to create customizable NFTs with interchangeable traits. My platform currently uses ERC-721 for NFTs, but I need to upgrade it to ERC721A to optimize gas usage and improve minting efficiency.

Here's the situation:

I have JSON ABI files for my smart contracts, but I do not have access to the original Solidity .sol files.
I am using Wagmi for Web3 integration and my frontend is built with Next.js.
The platform works as expected, but I need to upgrade ERC-721 to ERC721A.
What I need help with:

How can I upgrade from ERC-721 to ERC721A using only the JSON ABI files? Since I don't have access to the Solidity source code, can I still upgrade the contract via ABI files?
Are there any existing libraries or tools that can help me with this upgrade process using just the ABI files?
What I have tried:
I've looked into ERC721A and found that the typical upgrade process involves access to the Solidity source code, but I don't have that in my case.
I explored options for interacting with my contract via ethers.js and Wagmi, but I am unsure of how to handle the upgrade with only the ABI.
I've reviewed various resources and tutorials, but they mostly assume access to the Solidity source code for re-compiling and upgrading.
What I expect:
I'm looking for guidance on how to approach upgrading my ERC-721 contract to ERC721A if I have only the JSON ABI files. Is there a way to modify the contract behavior using just the ABI, or do I need to deploy a new contract entirely?

Additional Context:
I'm using Wagmi for Web3 integration in Next.js.
The contract is already deployed, and I have the JSON ABI files but no access to the Solidity code.
Thank you in advance for any suggestions or resources that could help!

Upgrading your ERC-721 contract to ERC721A with only the ABI files presents some challenges due to the limitations of ABI files, as they only define the interface and not the actual implementation. Here's how you can proceed:

1. Understand the Limitations

ABI Files:

Allow you to interact with deployed contracts but do not grant the ability to modify the underlying smart contract code or its behavior.

Upgradeability:

Direct upgrades to a deployed contract are not possible unless the contract was designed to be upgradeable (e.g., using a proxy pattern like OpenZeppelin's TransparentUpgradeableProxy).

2. Options for Moving Forward

Option A: Deploy a New Contract

Recreate the Contract:

Since you lack access to the original Solidity code, you'll need to write a new implementation using ERC721A.
Migrate your existing metadata and NFT state to the new contract. This process involves:
Snapshotting Data: Query the current state of your NFTs (e.g., ownership, metadata) using the existing ABI.
Redeploying with ERC721A: Write a new ERC721A-based contract and deploy it.
Migrating Data: Use scripts to transfer metadata and other stateful information to the new contract.

Frontend Adjustments:

Update your Wagmi integration to point to the new contract address and ABI.

Option B: Layering New Logic

Extend via Middleware or Frontend:

If redeployment isn't feasible, you can simulate ERC721A-like optimizations in your application layer by batching transactions or optimizing user interactions.
Example: Batch minting calls using the existing ABI to reduce gas costs for users.
