After [configuring the object storage](../../uploads.md#Using object storage) for GitLab's uploads, you may use this task to migrate existing uploads from the local storage to the remote storage.
>**Note:**
All of the processing will be done in a background worker and requires **no downtime**.
This tasks uses 3 parameters to find uploads to migrate.
>**Note:**
These parameters are mainly internal to GitLab's structure, you may want to refer to the task list instead below.
Parameter | Type | Description
--------- | ---- | -----------
`uploader_class` | string | Type of the uploader to migrate from
`model_class` | string | Type of the model to migrate from
`mount_point` | string/symbol | Name of the model's column on which the uploader is mounted on.
This task also accepts some environment variables which you can use to override
certain values:
Variable | Type | Description
-------- | ---- | -----------
`BATCH` | integer | Specifies the size of the batch. Defaults to 200.
Uploads represent all user-data that may be sent to GitLab as a single file. As an example, avatars and notes' attachments are uploads. Uploads are integral to GitLab functionality, and therefore cannot be disabled.
### Using local storage
>**Notes:**
This is the default configuration
To change the location where the artifacts are stored locally, follow the steps
below.
---
**In Omnibus installations:**
>**Notes:**
For historical reasons, uploads are stored into a base directory, which by default is `uploads/-/system`. It is strongly discouraged to change this configuration option on an existing GitLab installation.
_The uploads are stored by default in `/var/opt/gitlab/gitlab-rails/public/uploads/-/system`._
1. To change the storage path for example to `/mnt/storage/uploads`, edit
`/etc/gitlab/gitlab.rb` and add the following line:
1. Save the file and [reconfigure GitLab][] for the changes to take effect.
1. Migrate any existing local uploads to the object storage:
>**Notes:**
These task comply with the `BATCH` environment variable to process uploads in batch (200 by default). All of the processing will be done in a background worker and requires **no downtime**.
Currently this has to be executed manually and it will allow you to
migrate the existing uploads to the object storage, but all new
uploads will still be stored on the local disk. In the future
you will be given an option to define a default storage for all
new files.
---
**In installations from source:**
_The artifacts are stored by default in
`/home/git/gitlab/public/uploads/-/system`._
1. Edit `/home/git/gitlab/config/gitlab.yml` and add or amend the following
lines:
```yaml
uploads:
object_store:
enabled: true
remote_directory: "uploads" # The bucket name
connection:
provider: AWS # Only AWS supported at the moment
aws_access_key_id: AWS_ACESS_KEY_ID
aws_secret_access_key: AWS_SECRET_ACCESS_KEY
region: eu-central-1
```
1. Save the file and [restart GitLab][] for the changes to take effect.
1. Migrate any existing local artifacts to the object storage:
>**Notes:**
- These task comply with the `BATCH` environment variable to process uploads in batch (200 by default). All of the processing will be done in a background worker and requires **no downtime**.
- To migrate in production use `RAILS_ENV=production` environment variable.
