SharePoint Migration Tool - First Impressions

I also received the Scan File Failure:Not enough disk space to pack the file.

This is using version 0.2.68.0

I have run test runs successfully on previous versions of this tool and foolishly upgraded to the latest version before attempting to go live this weekend with the full site. My previous migrations were just taking a subdirectory of my source and migrating that. The only issue I was having was the permissions getting reset on the destination sharepoint directory and locking everyone out (but easy enough to fix).

My source directory is 22.3GB of content with 24gb of free space and my temp drive (which I am assume it is writing to) has 203GB free. The log file directory is being written to %appdata% which in my case is a network share if that would help diagnose the issue.
