GitHub Organization Migration Plan

​

Migration Options

​

Option 1: Simple Transfer (GitHub Built-in)

​

What Transfers Automatically

• All branches and commit history
• Git tags and annotated tags

• Issues and pull requests (with all comments)
• Projects (classic and new)
• Releases and release assets
• Milestones and labels

• Stars and watchers
• Wiki content
• Fork relationships

• Webhooks configurations
• Deploy keys
• Repository-level secrets
• GitHub Actions workflows
• Git LFS objects (copied in background)

​

What Needs Manual Updates

• Branch protection rules (inherits new org defaults - review carefully)
• Organization-level secrets (must recreate in new org)
• Environment-level secrets (if used outside repo scope)
• Team permissions (reassign in new org structure)

• CI/CD systems with hardcoded URLs
• Documentation with repository links
• Package registries (npm, etc.)
• External webhooks
• Status badges in README

​

Option 2: Migration with History Cleanup

1. Removes large files from history
2. Cleans up accidental commits
3. Preserves important history
4. Maintains all issues, PRs, and project management features

​

Pre-Migration Checklist

​

Preparation (1-2 days before)

• Prepare Target Organization
  • Create vibetunnel organization if not exists
  • Set up teams and permissions structure
  • Configure organization-level settings
  • Review default branch protection rules
• Audit Current Setup
  • Document all webhooks and integrations
  • List organization/environment secrets
  • Note branch protection rules
  • Identify external services using the repo
• Analyze Repository for Cleanup (if using Option 2)
  # Find large files in history
  git rev-list --objects --all | \
    git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' | \
    awk '/^blob/ && $3 > 10485760 {print $3, $4}' | \
    sort -rn | \
    numfmt --field=1 --to=iec
  
• Notify Stakeholders
  • Team members about the migration
  • Users via issue/discussion if needed
  • Update any public documentation

​

Migration Process

​

Option 1: Simple Transfer Steps

1. Navigate to Settings → General → Danger Zone → Transfer
2. Enter the new owner: vibetunnel
3. Type the repository name to confirm
4. Accept the invite from the destination org
5. Done! ✅

​

Option 2: Clean Migration Script

#!/bin/bash
set -euo pipefail

# Configuration
OLD_REPO="git@github.com:amantus-ai/vibetunnel.git"
NEW_REPO="git@github.com:vibetunnel/vibetunnel.git"
TEMP_DIR="vibetunnel-migration-$(date +%Y%m%d-%H%M%S)"
SIZE_THRESHOLD="10M"  # Files larger than this will be removed

echo "🚀 Starting VibeTunnel repository migration with cleanup..."

# Create temporary directory
mkdir -p "$TEMP_DIR"
cd "$TEMP_DIR"

# Clone the repository (all branches and tags)
echo "📥 Cloning repository with all history..."

# Create a backup first

  awk '/^blob/ {print substr($0,6)}' | \
  sort --numeric-sort --key=2 --reverse | \
  awk '$2 >= 10485760 {print $1, $2, $3}' > ../large-files.txt

echo "📊 Large files found:"
cat ../large-files.txt | while read hash size path; do
  echo "  - $path ($(numfmt --to=iec $size))"
done

# Download BFG Repo-Cleaner if not available
if ! command -v bfg &> /dev/null && [ ! -f ../bfg.jar ]; then
  echo "📦 Downloading BFG Repo-Cleaner..."
  curl -L -o ../bfg.jar https://repo1.maven.org/maven2/com/madgag/bfg/1.14.0/bfg-1.14.0.jar
fi

# Clean large files using BFG
echo "🧹 Removing large files from history..."
java -jar ../bfg.jar --strip-blobs-bigger-than "$SIZE_THRESHOLD" --no-blob-protection

# Clean specific file patterns (customize as needed)
echo "🗑️  Removing unwanted file patterns..."
java -jar ../bfg.jar --delete-files '*.{log,tmp,cache}' --no-blob-protection
java -jar ../bfg.jar --delete-folders '{node_modules,dist,build}' --no-blob-protection

# Clean up the repository
echo "♻️  Cleaning up repository..."
git reflog expire --expire=now --all
git gc --prune=now --aggressive

# Show size comparison
echo "📏 Size comparison:"
cd ..
ORIGINAL_SIZE=$(du -sh vibetunnel-backup | cut -f1)
CLEANED_SIZE=$(du -sh vibetunnel-mirror | cut -f1)
echo "  Original: $ORIGINAL_SIZE"
echo "  Cleaned:  $CLEANED_SIZE"

# Update remote URL and push
cd vibetunnel-mirror
git remote set-url origin "$NEW_REPO"

# Interactive confirmation
echo "⚠️  Ready to push to $NEW_REPO"
read -p "Continue? (y/N) " -n 1 -r
echo
if [[ ! $REPLY =~ ^[Yy]$ ]]; then
  echo "❌ Aborted"
  exit 1
fi

# Push to new repository
echo "📤 Pushing to new repository..."
git push --mirror "$NEW_REPO"

echo "✅ Migration complete!"

​

Post-Migration Updates

​

Update Git Remotes

# For all local clones
git remote set-url origin git@github.com:vibetunnel/vibetunnel.git

# Verify the change
git remote -v

​

Update VibeTunnel Code

• Update GITHUB_URL in mac/VibeTunnel/version.xcconfig
• Update repository URLs in all package.json files:
  {
    "repository": {
      "type": "git",
      "url": "git+https://github.com/vibetunnel/vibetunnel.git"
    },
    "bugs": {
      "url": "https://github.com/vibetunnel/vibetunnel/issues"
    },
    "homepage": "https://github.com/vibetunnel/vibetunnel#readme"
  }
  
• Update any hardcoded GitHub URLs in documentation
• Update CLAUDE.md references
• Update docs.json if it contains repository URLs

​

Update External Services

• CI/CD configurations
• npm package registry URLs
• Monitoring services
• Documentation sites
• README badges and links
• Installation instructions
• Contributing guidelines

​

Build & Release

• Update GitHub Actions secrets if needed
• Verify macOS notarization still works
• Test release workflow with new repo URL
• Update Sparkle appcast URLs if applicable
• Consider publishing a patch version with updated URLs

​

Redirect Behavior

• https://github.com/amantus-ai/vibetunnel → https://github.com/vibetunnel/vibetunnel
• Git operations: git clone git@github.com:amantus-ai/vibetunnel.git still works
• API calls to old URL redirect automatically

• Redirects break if someone creates a new repo at amantus-ai/vibetunnel
• Some tools may not follow redirects properly
• Best practice: Update all references ASAP

​

Timeline

• Set up new organization
• Audit current configuration
• Notify team

• Morning: Final preparations
• Midday: Execute transfer
• Afternoon: Update configurations

• Test all integrations
• Monitor for issues
• Complete documentation updates

​

Important Notes

• GitHub’s transfer process is well-tested and reliable
• The automatic redirects provide good backward compatibility
• If using history cleanup (Option 2):
  • This process rewrites history - all commit SHAs will change
  • Contributors will need to re-clone or rebase their work
  • Keep the cleaned backup for a few weeks
• Consider doing this during a low-activity period

​

Rollback Plan

1. GitHub Support can reverse transfers within a short window
2. Keep the migration backup (if using Option 2)
3. Document any issues for future reference
