Copy GitHub Repository PowerShell migration toolkit

GitHub host support

The current 0.4.x release line supports GitHub.com only.

The public -HostName parameter remains part of the command contract so GitHub Enterprise support can be added without redesigning the public API. For the current 0.4.x release line, the supported value is github.com (case-insensitive).

All four public commands fail closed for any other hostname:

  • Copy-GitHubRepository
  • Get-GitHubRepository
  • Start-CopyGitHubRepositoryWizard
  • Test-GitHubRepositoryMigration

Unsupported hosts produce the structured GitHubHostNotSupported error before prerequisite checks, repository discovery, planning, verification, or remote mutation begin.

This fail-closed behavior prevents repository discovery through one GitHub host while a later operation implicitly targets another host. GitHub Enterprise Server and other GitHub hosts remain outside the current 0.4.x product contract.
