If the absolute filepath is the same in the machines (since SHA-1 hash of
filepath is used as engineVersion), there would be no changes in the above
workflow. You can just copy the engine directory and deploy. If not, you
can also provide engine-id, engine-version as CLI arguments.
There's some additional ongoing work to make the process more robust and
clearer, such as enabling engine-directory as CLI input, help messages, and
adding tests to cover such scenarios. I don't think the PR will be merged
before then.
