Cannot import local storage nugets via Nuget.Server import

[AlbertoBN]

Describe the bug

I have a local storage feed run under Nuget.Server. I am trying to upgrade to BaGet and no matter what I do I get an error. BaGet is running behind IIS. Tried in console and IIS mode with no results

To Reproduce

Steps to reproduce the behavior:

1. Using this version of BaGet 'v0.3.0-preview4'
2. Running the script from the Nuget.Server folder as per the documentation for importing Nuget.Server
3. With these arguments - as per documentation
4. See error - redacted

nuget.exe push -Source http://localhost:5060/v3/index.json "Packages\***********.nupkg"
Pushing ******** to 'http://localhost:5060/v3/index.json'...
Failed to process request. 'Method Not Allowed'.
The remote server returned an error: (405) Method Not Allowed..

Expected behavior

Packages are pushed and visible in BaGet UI

Found a workaround in the import script replace

Write-Host "nuget.exe push -Source $destination ""$path""" & nuget.exe push -Source $destination $path

With

Write-Host "dotnet push -k <apikeyifyouhave> -s $destination ""$path""" & dotnet push -k <apikeyifyouhave> -s $destination ""$path"""

Maybe the documentation is outdated?
