Step Three: Apply Patches

The final step of the cluster migration process is to apply all the patches generated by the Transform command to exported resources.

crane apply -e export -t transform -o output

Apply the patches in the transform directory to the resources in the export directory and save the modified resource files in the output directory.

After applying the patches, the resources located in output directory can either be deployed to the destination cluster using kubectl apply, or they can be pushed to a repository and then applied with the help of the GitOps pipeline. An example of the later scenario can be found here.
