#!/bin/bash

# ====== USAGE ======
#
# ./tranfer_git_repository.sh <old_git_url> <target_git_url>
#
# Example:
# ./transfer_git_repository.sh https://<access_token>@git.example.com/Organization1/repo-name https://<access_token>@git.example.com/Organization2/repo-name

# Script arguments
old_repo_url="$1"  # URL of the original remote repository (e.g., https://<token>@github.com/user/repo.git)
new_repo_url="$2"  # URL of the new remote repository (e.g., https://<token>@yourserver.com/user/repo.git)
repo_name="${old_repo_url##*/}"  # Extract repository name from old URL

# Check if required arguments are provided
if [ -z "$old_repo_url" ] || [ -z "$new_repo_url" ]; then
  echo "Error: Please provide both old and new repository URLs as arguments."
  exit 1
fi

# Clone the old repository (bare clone recommended for efficiency)
git clone --bare "$old_repo_url" "$repo_name"

# Enter the old repository
cd "$repo_name";

# Add the new remote repository
git remote add new-origin "$new_repo_url"

# Push all branches and tags to the new remote repository
git push --mirror new-origin

# Remove the temporary local repository (if using bare clone)
if [ "$(git config --local --get remote.new-origin.url)" == "$new_repo_url" ]; then
  rm -rf "$repo_name"
fi

echo "Successfully transferred repository '$repo_name' from '$old_repo_url' to '$new_repo_url'"

# Cleanup, remove the old repository
rm -rf "$repo_name";
