Migrate NuGet Packages Between GitHub Instances

Migrate NuGet packages from one GitHub instance to another

This should be able to migrate packages from GitHub Enterprise Server to GitHub.com using the <source-host> parameter. If GitHub.com to GitHub.com, set <source-host> to github.com.

Note See accompanying blog post! 🚀

Prerequisites

1. gh cli installed
2. Set the source GitHub PAT env var: export GH_SOURCE_PAT=ghp_abc (must have at least read:packages, read:org scope)
3. Set the target GitHub PAT env var: export GH_TARGET_PAT=ghp_xyz (must have at least write:packages, read:org scope)

Notes:

• This script installs gpr locally to the ./temp/tools directory
• This script assumes that the target org's repo name is the same as the source
• If the repo doesn't exist, the package will still import but won't be mapped to a repo

Usage

./migrate-nuget-packages-between-orgs.sh \
  <source-org> \
  <source-host> \
  <target-org>

Example

export GH_SOURCE_PAT=ghp_abc
export GH_TARGET_PAT=ghp_xyz

./migrate-nuget-packages-between-orgs.sh \
  joshjohanning-org-packages \
  github.com \
  joshjohanning-org-packages-migrated

Run this to clean up your working dir: rm ./*.nupkg ./*.zip

Notes

• Uses jcansdale/gpr to do the nuget push
• Had to delete _rels/.rels and [Content_Types].xml because there was somehow two copies of each file in the package and it causes gpr to fail when extracting/zipping the package to re-push
• Run this to clean up your working directory: rm -rf ./temp
