## git-filter-repo

- Stage a working area. These are somewhat throwaway directories and local git repos.
- clone both source and target repos.
```
mkdir my-working-dir
cd my-working-dir
git clone git@github.com:bonovoxly/source.git
git clone git@github.com:bonovoxly/target.git
```

### In source repo

We checkout a branch that we will filter against. We specify the path(s) that we want.

```
cd ./source
git checkout filter-source
git filter-repo --path ansible/ansible.cfg --path ansible/file.yml --path ansible/another-file.yml --refs refs/heads/filter-source --force
```

## In target repo

```
cd ../target
git checkout -b filter-target
git remote add repo-source ../source
git fetch repo-source
git branch branch-source remotes/repo-source/filter-source
git merge branch-source --allow-unrelated-histories
```

This worked perfectly for me. I was able to migrate a large number of files from one repo to another and retain the git history.

The nice thing is, if something goes wrong, you can just checkout main, delete the branch, start all over.

This did not work for me, when I checkout out main it was empty. I had to clone again. Great gist though.

It can really be simplified when pushing to a blank repository. After the filter
git remote add origin https://
git branch -M main
git push -u origin main
