Migrate to 2.0 Lifecycle, Hyperledger Fabric EVM

Question

I'm trying, without much luck, to compile the EVM chaincode that is been packed with Hyperledger Fabric from https://github.com/hyperledger/fabric-chaincode-evm

It is required for us to compile this to version 2.0.1 of the ledger since that's what our network uses, everything runs fine, I managed to compile with the fabric v2.0.0 dependency inside the go.mod dependencies file and later on pulled the missing 1.4.0 dependencies (peer, shim) with

go get github.com/hyperledger/fabric/protos/peer
go get github.com/hyperledger/fabric/core/chaincode/shim

Also changed integration/vendor/github.com/hyperledger/fabric/protos/common/configuration.proto from 1 to 2, like so:

message Capabilities {
    map<string, Capability> capabilities = 2;
}

However, when making instantiation I'm getting an error:

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg Channel 'evm' has been migrated to the new lifecycle, LSCC is now read-only

I'm not sure where can I change the flag to use the new lifecycle inside the EVM chaincode, I'm not a go expert, so I better put this as a question and rely on more expert developers.

How can I upgrade to the new lifecycle?

I think I'm missing the command parameters to approve the chaincode for all the peers inside the network, I'm trying

peer lifecycle chaincode approveformyorg -o orderer.example.com:7050 --channelID evm --name evmcc --version ${EVM_VERSION} --init-required --package-id ${PACKAGE_ID} --sequence ${EVM_VERSION} --waitForEvent

But I don't know how to extract the package-id from an installed chaincode package.

Thanks in advance.

It got solved by using invoke.

Instead of instantiating first we approve for the org, then invoke for each peer in the network. Like so:

export PEER_CONN_PARMS="--peerAddresses $ORG1_PEER0_CORE_PEER_ADDRESS --peerAddresses $ORG1_PEER1_CORE_PEER_ADDRESS --peerAddresses $ORG2_PEER0_CORE_PEER_ADDRESS --peerAddresses $ORG2_PEER1_CORE_PEER_ADDRESS --tlsRootCertFiles $ORG1_PEER0_CORE_PEER_TLS_ROOTCERT_FILE --tlsRootCertFiles $ORG1_PEER1_CORE_PEER_TLS_ROOTCERT_FILE --tlsRootCertFiles $ORG2_PEER0_CORE_PEER_TLS_ROOTCERT_FILE --tlsRootCertFiles $ORG2_PEER1_CORE_PEER_TLS_ROOTCERT_FILE"

echo $PEER_CONN_PARMS
