Steps to reproduce

Hi, I am trying to migrate older project created in VS15 by running the command:
dotnet migrate --skip-backup -s -x "c:\SRC\IT\Approvals\AdminPortal\Approvals\Approvals.xproj" "c:\SRC\IT\Approvals\AdminPortal\Approvals\project.json" --format-report-file-json

Any ideas would be appreciated. Thank you

Actual behavior

First I get the error message saying "dotnet has stoped working" with error message in the console:

c:\SRC\IT\Approvals\AdminPortal>dotnet migrate --skip-backup -s -x "c:\SRC\IT\Approvals\AdminPortal\Approvals\Approvals.xproj" "c:\SRC\IT\Approvals\AdminPortal\Approvals\project.json" --format-report-file-json
Migration failed.
