I installed a new 2012 R2 with Zen2017. And now I would like to export the bundles from the 2008 server (ZEN 11.4) as naturally as possible for the new server.

If I export a bundle and then import into 2017, he verifies everything as positive, but he does not simply load the bundle. Status permanently on 0 (a small bundle like 7zip).
I go into Zen2017 on Bundles / New / Bundle import / upload directory. On the next page (step 2), the bundle is displayed as a green checkmark in the validation status. After I go to "Finish", is displayed with corresponding overview. From here it does not go any further ...

Look at my Screenshot:

And this is the second screenshot with the 0% status:

What is the problem? Is there any log?
