I'm having some issues with the VPP migration tool. After a while the tool stops while giving this message:

The source VPP files are on a network share and the destination blobs-folder is on the same share. I've been able to run the migration sucessfully in my local dev-environment; where both the tool, the original VPP files and the blobs-desitination folder is located.

As a side-note I noticed that the original VPP folders are ~9,5 GB (81k files), while the migrated folders are ~3,75 GB (72k files) in size.  Is this normal?

Anyone else experiencing these errors?

Also, I found this in the event viewer log:

I have seen that exception before. In that case it was caused by that the zip (that was downloaded from internet) was "blocked". The solution was to rightclick on the zip from windows explorer and choose "unblock" before unzipping it.

However - In my case there is nothing to unblock (no unblock button is showing while viewing properties on the zip-file).

Also, I suppose I shouldn't have been able to migrate as much as ~81 000 files if that was the case?

I did another test. I downloaded the most recent VPP-files and production database to my local environement, and were able to run the VPP tool without any error message. It took about 1,5 hours.

So I'll probably do the same when performing the upgrade on our live servers, and just uploaded the updated database and blobs-directory back when done.

I'm thinking the combination of network shared VPP source+destination, combined with a rather limited test-server, in terms of cpu/mem./disk, may be the cause of the error in the VPP tool. But I'm not sure.
