PowerShell module to copy the contents of one PowerShell NuGet repository to another

If you have PS 5.0 or above, you can install from PowerShell Gallery using

Install-Module NuSync

Otherwise you can download the module as a zip and re You must have already registered the source and destination repositories that you wish to copy to and from using Register-PSRepository. The names you specified when registering those repositories will be what you pass as -SourceRepository and -DestinationRepository.

Be warned that you must not have versions of modules in the destination repository newer than those you wish to sync from the source.
This module works best when run as the sole module publisher for the destination as it orders the version uploads such that the oldest version will be uploaded first, and the latest last (otherwise Publish-Module will complain about you rewriting your version history!).

You may wish to set $ProgressPreference="SilentlyContinue" when running this module because Publish-Module's output becomes somewhat overwhelming during the publishing phase.

$SourceRepository = "DevGallery"
$DestinationRepository = "TestGallery"
$NugetApiKey = "xxxxxxx-xxx-xxx-xxx-xxxxxxxxxxxx"

Install-Module NuSync -Repository PSGallery
Import-Module NuSync
Sync-NSModule -SourceRepository $SourceRepository -DestinationRepository $DestinationRepository -NugetApiKey $NugetApiKey -Verbose
