If you are already familiar with the Weaver Getting Started tutorial, you can compare it with the corresponding tutorial for Weaver components within Cacti. The instructions are almost identical, with differences in the names of packages, images, and modules, either in configuration files or in public repositories.
The entire source code of github.com/hyperledger-labs/weaver-dlt-interoperability (https://github.com/hyperledger-labs/weaver-dlt-interoperability) was migrated to the weaver folder within github.com/hyperledger/cacti (https://github.com/hyperledger/cacti/tree/main/weaver). As a developer/contributor, you can compare the two and note recent changes made to the latter.
Weaver philosophy and usage was documented in https://labs.hyperledger.org/weaver-dlt-interoperability/docs/external/introduction. The philosophy and usage of Weaver components as part of the Cacti framework are now documented in https://hyperledger.github.io/cacti/weaver/introduction/.
Users can compare the instructions for setting up test networks and testing protocols in https://labs.hyperledger.org/weaver-dlt-interoperability/docs/external/getting-started/guide with the newer Cacti version in https://hyperledger.github.io/cacti/weaver/getting-started/guide/. The instructions look very similar; only the references (URLs, package names, Docker image names, etc.) have changed.
Below we list the published Weaver packages and images, and their corresponding published Cacti packages and images.

-
To deploy the Fabric Interop Chaincode in your Fabric network:
- You would import the Weaver package
github.com/hyperledger-labs/weaver-dlt-interoperability/core/network/fabric-interop-cc/contracts/interop(as in https://github.com/hyperledger-labs/weaver-dlt-interoperability/blob/main/tests/network-setups/fabric/dev/scripts/setupCC.sh). - Instead, you should now import the Cacti package
github.com/hyperledger/cacti/weaver/core/network/fabric-interop-cc/contracts/interop(as in https://github.com/hyperledger/cacti/blob/main/weaver/tests/network-setups/fabric/dev/scripts/setupCC.sh)
- You would import the Weaver package
-
To deploy the Corda Driver in your Corda network:
- You would pull the Weaver Docker image
ghcr.io/hyperledger-labs/weaver-corda-driver(as in https://github.com/hyperledger-labs/weaver-dlt-interoperability/blob/main/core/drivers/corda-driver/docker-testnet-envs/.env.corda) - Instead, you should now import the Cacti Docker image
