Hello I am trying to merge two different versions of subgraph data

The scenario is I am trying to setup a subgraph for my NFT project and after some time, I will fine issue in the Contract then I update the contract and redeploy the smart contract and subgraph but in the new graph, I didn't find the old data can anyone help me, in this case, thank you.

@touqeerShah Which subgraph are you talking about in lesson 14?

[touqeerShah]

I know that how to upgrade the but

let's suppose you did a few transactions in the first contract and subgraph index that data but when you upgrade now address of a contract is changed and you redeploy the subgraph but you didn't see the old transactions data which are linked to the old contract

@touqeerShah That is not possible, and leave a graph. Can you move one contract transaction to another contract?

[touqeerShah]

no i want to move one index subgraph data to new version of subgraph
