# Migration guide from Git Annex to Git LFS
>**Note:**
Git Annex support [has been removed][issue-remove-annex] in GitLab Enterprise
Edition 9.0 (2017/03/22).
Both [Git Annex][] and [Git LFS][] are tools to manage large files in Git.
## History
Git Annex [was introduced in GitLab Enterprise Edition 7.8][post-3], at a time
where Git LFS didn't yet exist. A few months later, GitLab brought support for
Git LFS in [GitLab 8.2][post-2] and is available for both Community and
Enterprise editions.
## Differences between Git Annex and Git LFS
Some items below are general differences between the two protocols and some are
ones that GitLab developed.
- Git Annex works only through SSH, whereas Git LFS works both with SSH and HTTPS
(SSH support was added in GitLab 8.12).
- Annex files are stored in a sub-directory of the normal repositories, whereas
LFS files are stored outside of the repositories in a place you can define.
- Git Annex requires a more complex setup, but has much more options than Git
LFS. You can compare the commands each one offers by running `man git-annex`
and `man git-lfs`.
- Annex files cannot be browsed directly in GitLab's interface, whereas LFS
files can.
## Migration steps
>**Note:**
Since Git Annex files are stored in a sub-directory of the normal repositories
(`.git/annex/objects`) and LFS files are stored outside of the repositories,
they are not compatible as they are using a different scheme. Therefore, the
migration has to be done manually per repository.
There are basically two steps you need to take in order to migrate from Git
Annex to Git LFS.
### TL; DR
If you know what you are doing and want to skip the reading, this is what you
need to do (we assume you have [git-annex enabled](../git_annex.md#using-gitlab-git-annex) in your
repository and that you have made backups in case something goes wrong).
Fire up a terminal, navigate to your Git repository and:
1. Disable `git-annex`:
```shell
git annex sync --content
git annex direct
git annex uninit
git annex indirect
```
1. Enable `git-lfs`:
```shell
git lfs install
git lfs track <files>
git add .
git commit -m "commit message"
git push
```
### Disabling Git Annex in your repo
Before changing anything, make sure you have a backup of your repository first.
There are a couple of ways to do that, but you can simply clone it to another
local path and maybe push it to GitLab if you want a remote backup as well.
Here you'll find a guide on
[how to back up a **git-annex** repository to an external hard drive][bkp-ext-drive].
Since Annex files are stored as objects with symlinks and cannot be directly
modified, we need to first remove those symlinks.
NOTE: **Note:**
Make sure the you read about the [`direct` mode][annex-direct] as it contains
useful information that may fit in your use case. Note that `annex direct` is
deprecated in Git Annex version 6, so you may need to upgrade your repository
if the server also has Git Annex 6 installed. Read more in the
[Git Annex troubleshooting tips](../git_annex.md#troubleshooting-tips) section.
1. Backup your repository
```shell
cd repository
git annex sync --content
cd ..
git clone repository repository-backup
cd repository-backup
git annex get
cd ..
```
1. Use `annex direct`:
```shell
cd repository
git annex direct
```
The output should be similar to this:
```shell
commit
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working tree clean
ok
direct debian.iso ok
direct ok
```
1. Disable Git Annex with [`annex uninit`][uninit]:
```shell
git annex uninit
```
The output should be similar to this:
```shell
unannex debian.iso ok
Deleted branch git-annex (was 2534d2c).
```
This will `unannex` every file in the repository, leaving the original files.
1. Switch back to `indirect` mode:
```shell
git annex indirect
```
The output should be similar to this:
```shell
(merging origin/git-annex into git-annex...)
(recording state in git...)
commit (recording state in git...)
ok
(recording state in git...)
[master fac3194] commit before switching to indirect mode
1 file changed, 1 deletion(-)
delete mode 120000 alpine-virt-3.4.4-x86_64.iso
ok
indirect ok
ok
```
---
redirect_to: '../../topics/git/lfs/migrate_from_git_annex_to_git_lfs.md'
---
At this point, you have two options. Either add, commit and push the files
directly back to GitLab or switch to Git LFS. We will tackle the LFS switch in
the next section.
### Enabling Git LFS in your repo
Git LFS is enabled by default on all GitLab products (GitLab CE, GitLab EE,
GitLab.com), therefore, you don't need to do anything server-side.
1. First, make sure you have `git-lfs` installed locally:
```shell
git lfs help
```
If the terminal doesn't prompt you with a full response on `git-lfs` commands,
[install the Git LFS client][install-lfs] first.
1. Inside the repo, run the following command to initiate LFS:
```shell
git lfs install
```
1. Enable `git-lfs` for the group of files you want to track. You
can track specific files, all files containing the same extension, or an
entire directory:
```shell
git lfs track images/01.png # per file
git lfs track **/*.png # per extension
git lfs track images/ # per directory
```
Once you do that, run `git status` and you'll see `.gitattributes` added
to your repo. It collects all file patterns that you chose to track via
`git-lfs`.
1. Add the files, commit and push them to GitLab:
```shell
git add .
git commit -m "commit message"
git push
```
If your remote is set up with HTTP, you will be asked to enter your login
credentials. If you have [2FA enabled](../../user/profile/account/two_factor_authentication.md), make sure to use a
[personal access token](../../user/profile/account/two_factor_authentication.md#personal-access-tokens)
instead of your password.
## Removing the Git Annex branches
After the migration finishes successfully, you can remove all `git-annex`
related branches from your repository.
On GitLab, navigate to your project's **Repository ➔ Branches** and delete all
branches created by Git Annex: `git-annex`, and all under `synced/`.
![repository branches](img/git-annex-branches.png)
You can also do this on the command line with:
```shell
git branch -d synced/master
git branch -d synced/git-annex
git push origin :synced/master
git push origin :synced/git-annex
git push origin :git-annex
git remote prune origin
```
If there are still some Annex objects inside your repository (`.git/annex/`)
or references inside `.git/config`, run `annex uninit` again:
```shell
git annex uninit
```

At this point, you have two options. Either add, commit and push the files

the next section.
### Enabling Git LFS in your repo
Git LFS is enabled by default on all GitLab products (GitLab CE, GitLab EE,

1. First, make sure you have `git-lfs` installed locally:
```shell

If the terminal doesn't prompt you with a full response on `git-lfs` commands,
[install the Git LFS client][install-lfs] first.
1. Inside the repo, run the following command to initiate LFS:
```shell

1. Enable `git-lfs` for the group of files you want to track. You
can track specific files, all files containing the same extension, or an

```
Once you do that, run `git status` and you'll see `.gitattributes` added
to your repo. It collects all file patterns that you chose to track via
`git-lfs`.
1. Add the files, commit and push them to GitLab:
```shell

[personal access token](../../../user/profile/account/two_factor_authentication.md#personal-access-tokens)
instead of your password.
## Removing the Git Annex branches
After the migration finishes successfully, you can remove all `git-annex`
related branches from your repository.
On GitLab, navigate to your project's **Repository ➔ Branches** and delete all
branches created by Git Annex: `git-annex`, and all under `synced/`.
![repository branches](img/git-annex-branches.png)
You can also do this on the command line with:
```shell
git branch -d synced/master
git branch -d synced/git-annex
git push origin :synced/master
git push origin :synced/git-annex
git push origin :git-annex
git remote prune origin
```
If there are still some Annex objects inside your repository (`.git/annex/`)
or references inside `.git/config`, run `annex uninit` again:
```shell
git annex uninit
```

# Migrate a Git repo into Git LFS with BFG
Using Git LFS can help you to reduce the size of your Git
repository and improve its performance.
However, simply adding the
large files that are already in your repository to Git LFS,
will not actually reduce the size of your repository because
the files are still referenced by previous commits.
Through the method described on this document, first migrate
to Git LFS with a tool such as the open source community-maintained [BFG](https://rtyley.github.io/bfg-repo-cleaner/)
through a mirror repo, then clean up the repository's history,
and lastly create LFS tracking rules to prevent new binary files
from being added.
This tutorial was inspired by the guide
[Use BFG to migrate a repo to Git LFS](https://confluence.atlassian.com/bitbucket/use-bfg-to-migrate-a-repo-to-git-lfs-834233484.html).
For more information on Git LFS, see the [references](#references)
below.
CAUTION: **Warning:**
The method described on this guide rewrites Git history. Make
sure to back up your repo before beginning and use it at your
own risk.
## Requirements
Before beginning, make sure:
- You have enough LFS storage for the files you want to convert.
Storage is required for the entire history of all files.
- All the team members you share the repository with have pushed all changes.
Branches based on the repository before applying this method cannot be merged.
Branches based on the repo before applying this method cannot be merged.
To follow this tutorial, you'll need:
- Maintainer permissions to the existing Git repository
you'd like to migrate to LFS with access through the command line.
- [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
and [Java Runtime Environment](https://www.java.com/en/download/manual.jsp)
(Java 7 or above) installed locally.
- BFG installed locally:
```shell
brew install bfg
```
- Git LFS installed locally:
```shell
brew install git-lfs
```
NOTE: **Note:**
This guide was tested on macOS Mojave.
## Steps
Consider an example upstream project, `git@gitlab.com:gitlab-tests/test-git-lfs-repo-migration.git`.
1. Back up your repository:
Create a copy of your repository so that you can
recover it in case something goes wrong.
1. Clone `--mirror` the repo:
Cloning with the mirror flag will create a bare repository.
This ensures you get all the branches within the repo.
It creates a directory called `<repo-name>.git`
(in our example, `test-git-lfs-repo-migration.git`),
mirroring the upstream project:
```shell
git clone --mirror git@gitlab.com:gitlab-tests/test-git-lfs-repo-migration.git
```
1. Convert the Git history with BFG:
```shell
bfg --convert-to-git-lfs "*.{png,mp4,jpg,gif}" --no-blob-protection test-git-lfs-repo-migration.git
```
It is scanning all the history, and looking for any files with
that extension, and then converting them to an LFS pointer.
1. Clean up the repository:
```shell
# cd path/to/mirror/repo:
cd test-git-lfs-repo-migration.git
# clean up the repo:
git reflog expire --expire=now --all && git gc --prune=now --aggressive
```
You can also take a look on how to further [clean the repo](../../../user/project/repository/reducing_the_repo_size_using_git.md),
but it's not necessary for the purposes of this guide.
1. Install Git LFS in the mirror repository:
```shell
git lfs install
```
1. [Unprotect the default branch](../../../user/project/protected_branches.md),
so that we can force-push the rewritten repository:
1. Navigate to your project's **Settings > Repository** and
expand **Protected Branches**.
1. Scroll down to locate the protected branches and click
**Unprotect** the default branch.
1. Force-push to GitLab:
```shell
git push --force
```
1. Track the files you want with LFS:
```shell
# cd path/to/upstream/repo:
cd test-git-lfs-repo-migration
# You may need to reset your local copy with upstream's `master` after force-pushing from the mirror:
git reset --hard origin/master
# Track the files with LFS:
git lfs track "*.gif" "*.png" "*.jpg" "*.psd" "*.mp4" "img/"
```
Now all existing the files you converted, as well as the new
ones you add, will be properly tracked with LFS.
1. [Re-protect the default branch](../../../user/project/protected_branches.md):
1. Navigate to your project's **Settings > Repository** and
expand **Protected Branches**.
1. Select the default branch from the **Branch** dropdown menu,
and set up the
**Allowed to push** and **Allowed to merge** rules.
1. Click **Protect**.
<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->

# Migrate a Git repo into Git LFS with BFG
Using Git LFS can help you to reduce the size of your Git
repository and improve its performance.
However, simply adding the
large files that are already in your repository to Git LFS,
will not actually reduce the size of your repository because
the files are still referenced by previous commits.
Through the method described on this document, first migrate
to Git LFS with a tool such as the open source community-maintained [BFG](https://rtyley.github.io/bfg-repo-cleaner/)
through a mirror repo, then clean up the repository's history,
and lastly create LFS tracking rules to prevent new binary files
from being added.
This tutorial was inspired by the guide
[Use BFG to migrate a repo to Git LFS](https://confluence.atlassian.com/bitbucket/use-bfg-to-migrate-a-repo-to-git-lfs-834233484.html).
For more information on Git LFS, see the [references](#references)
below.
CAUTION: **Warning:**
The method described on this guide rewrites Git history. Make
sure to back up your repo before beginning and use it at your
own risk.
## Requirements
Before beginning, make sure:
- You have enough LFS storage for the files you want to convert.
Storage is required for the entire history of all files.
- All the team members you share the repository with have pushed all changes.
Branches based on the repository before applying this method cannot be merged.
Branches based on the repo before applying this method cannot be merged.
To follow this tutorial, you'll need:
- Maintainer permissions to the existing Git repository
you'd like to migrate to LFS with access through the command line.
- [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
and [Java Runtime Environment](https://www.java.com/en/download/manual.jsp)
(Java 7 or above) installed locally.
- BFG installed locally:
```shell
brew install bfg
```
- Git LFS installed locally:
```shell
brew install git-lfs
```
NOTE: **Note:**
This guide was tested on macOS Mojave.
## Steps
Consider an example upstream project, `git@gitlab.com:gitlab-tests/test-git-lfs-repo-migration.git`.
1. Back up your repository:
Create a copy of your repository so that you can
recover it in case something goes wrong.
1. Clone `--mirror` the repo:
Cloning with the mirror flag will create a bare repository.
This ensures you get all the branches within the repo.
It creates a directory called `<repo-name>.git`
(in our example, `test-git-lfs-repo-migration.git`),
mirroring the upstream project:
```shell
git clone --mirror git@gitlab.com:gitlab-tests/test-git-lfs-repo-migration.git
```
1. Convert the Git history with BFG:
```shell
bfg --convert-to-git-lfs "*.{png,mp4,jpg,gif}" --no-blob-protection test-git-lfs-repo-migration.git
```
It is scanning all the history, and looking for any files with
that extension, and then converting them to an LFS pointer.
1. Clean up the repository:
```shell
# cd path/to/mirror/repo:
cd test-git-lfs-repo-migration.git
# clean up the repo:
git reflog expire --expire=now --all && git gc --prune=now --aggressive
```
You can also take a look on how to further [clean the repo](../../../user/project/repository/reducing_the_repo_size_using_git.md),
but it's not necessary for the purposes of this guide.
1. Install Git LFS in the mirror repository:
```shell
git lfs install
```
1. [Unprotect the default branch](../../../user/project/protected_branches.md),
so that we can force-push the rewritten repository:
1. Navigate to your project's **Settings > Repository** and
expand **Protected Branches**.
1. Scroll down to locate the protected branches and click
**Unprotect** the default branch.
1. Force-push to GitLab:
```shell
git push --force
```
1. Track the files you want with LFS:
```shell
# cd path/to/upstream/repo:
cd test-git-lfs-repo-migration
# You may need to reset your local copy with upstream's `master` after force-pushing from the mirror:
git reset --hard origin/master
# Track the files with LFS:
git lfs track "*.gif" "*.png" "*.jpg" "*.psd" "*.mp4" "img/"
```
Now all existing the files you converted, as well as the new
ones you add, will be properly tracked with LFS.
1. [Re-protect the default branch](../../../user/project/protected_branches.md):
1. Navigate to your project's **Settings > Repository** and
expand **Protected Branches**.
1. Select the default branch from the **Branch** dropdown menu,
and set up the
**Allowed to push** and **Allowed to merge** rules.
1. Click **Protect**.
