Hi,
I stumbled across this while looking for a way to copy a folder between a test and live app service on Azure.
Do you know if kudusync can be used to do this and how can i use it in a pipeline to do it?

Also I don't understand the point of the manifest files above - and why you set next and previous to be the same?
What does the content of this manifest file look like?

https://stackoverflow.com/questions/58580956/how-to-copy-a-folder-from-a-test-app-service-to-a-live-app-service-on-azure/58582499#58582499

Thanks.

@John-Blair Good question. I'm not sure why I set NEXT_MANIFEST_PATH and PREVIOUS_MANIFEST_PATH to be the same or if that's even needed. Maybe it was part of the boiler plate generated by kuduscript -- I don't remember. I did write about what I did in a post which you can view at https://alindgren.github.io/2017-12-17-deploying-to-azure-app-service-with-custom-build-script/ According to that, I actually ignore the manifest. I think I just copy everything from a temp build folder to the deployment target.

Thanks for the feedback! I managed to get my copy folder across app services working using kudo's zip directory feature - powershell script in link in original comment.
