Merge multiple repositories into one single repository

If you have created multiple repositories and now find it cluttered, you can merge them into a single repository while preserving all the commit history. Here’s how to do it.

1. Create a New Repository:

Create a new repository on GitHub or locally on your machine.

git init new-repo
cd new-repo

2. Add the Other Repositories as Remotes:

Add the repositories you want to merge as remotes in the new repository.

git remote add repo1 <url-of-repo1>
git remote add repo2 <url-of-repo2>

3. Fetch the Commits from the Other Repositories:

Fetch the commits from the other repositories.

git fetch repo1
git fetch repo2

4. Create New Branches for Each Repository:

Create new branches for each repository to bring in the files.

git checkout -b branch-repo1 repo1/main
git checkout -b branch-repo2 repo2/main

5. Move Files to Subdirectories:

Move the files from each branch to a subdirectory to avoid conflicts.

git checkout branch-repo1
mkdir repo1
git mv * repo1/
git commit -m "Moved repo1 files to subdirectory"

git checkout branch-repo2
mkdir repo2
git mv * repo2/
git commit -m "Moved repo2 files to subdirectory"

6. Merge the Branches into the Main Branch:

Merge the branches into the main branch and resolve any conflicts that may arise.

git checkout main
git merge branch-repo1
git merge branch-repo2

7. Push the Changes to the Remote Repository:

If you are using a remote repository, push the changes to it.

git remote add origin <url-of-new-repo>
git push -u origin main
