title: Exporting migration data from GitHub Enterprise Server
intro: 'To change platforms or move from a trial instance to a production instance, you can export migration data from a {% data variables.product.prodname_ghe_server %} instance by preparing the instance, locking the repositories, and generating a migration archive.'

## Preparing the {% data variables.product.prodname_ghe_server %} source instance
1. Verify that you are a site administrator on the {% data variables.product.prodname_ghe_server %} source. The best way to do this is to verify that you can [SSH into the instance]({% ifversion not ghes %}/enterprise-server@latest{% endif %}/admin/configuration/configuring-your-enterprise/accessing-the-administrative-shell-ssh).
1. {% data reusables.enterprise_migrations.token-generation %} on the {% data variables.product.prodname_ghe_server %} source instance.
{% data reusables.enterprise_migrations.make-a-list %}
## Exporting the {% data variables.product.prodname_ghe_server %} source repositories
{% data reusables.enterprise_migrations.locking-repositories %}
{% data reusables.enterprise_installation.ssh-into-instance %}
1. To prepare a repository for export, use the `ghe-migrator add` command with the repository's URL:
* If you're locking the repository, append the command with `--lock`. If you're performing a trial run, `--lock` is not needed.
```shell
ghe-migrator add https://HOSTNAME/USERNAME/REPO-NAME --lock
```
* You can exclude file attachments by appending `--exclude_attachments` to the command. {% data reusables.enterprise_migrations.exclude-file-attachments %}
* To prepare multiple repositories at once for export, create a text file listing each repository URL on a separate line, and run the `ghe-migrator add` command with the `-i` flag and the path to your text file.
```shell
ghe-migrator add -i PATH/TO/YOUR/REPOSITORY_URL.txt
```
1. When prompted, enter your {% data variables.product.prodname_ghe_server %} username:
```shell
Enter username authorized for migration: admin
```
1. When prompted for a {% data variables.product.pat_generic %}, enter the access token you created in [Preparing the {% data variables.product.prodname_ghe_server %} source instance](#preparing-the-github-enterprise-server-source-instance):
```shell
Enter {% data variables.product.pat_generic %}: **************
```
1. When `ghe-migrator add` has finished it will print the unique "Migration GUID" that it generated to identify this export as well as a list of the resources that were added to the export. You will use the Migration GUID that it generated in subsequent `ghe-migrator add` and `ghe-migrator export` steps to tell `ghe-migrator` to continue operating on the same export.
```shell
> 101 models added to export
> Migration GUID: EXAMPLE-MIGRATION-GUID
> Number of records in this migration:
> users | 5
> organizations | 1
> repositories | 1
> teams | 3
> protected_branches | 1
> pull_request_reviews | 1
> milestones | 1
> issues | 3
> pull_requests | 5
> pull_request_review_comments | 4
> commit_comments | 2
> issue_comments | 10
> issue_events | 63
> releases | 3
> attachments | 4
> projects | 2
```
Each time you add a new repository with an existing Migration GUID it will update the existing export. If you run `ghe-migrator add` again without a Migration GUID it will start a new export and generate a new Migration GUID. **Do not re-use the Migration GUID generated during an export when you start preparing your migration for import**.
1. To add more repositories to the same export, use the `ghe-migrator add` command with the `-g` flag. You'll pass in the new repository URL and the Migration GUID from Step 5:
```shell
ghe-migrator add https://HOSTNAME/USERNAME/OTHER-REPO-NAME -g MIGRATION-GUID --lock
```
1. When you've finished adding repositories, generate the migration archive using the `ghe-migrator export` command with the `-g` flag and the Migration GUID from Step 5:
```shell
$ ghe-migrator export -g MIGRATION-GUID
> Archive saved to: /data/github/current/tmp/MIGRATION-GUID.tar.gz
```
* {% data reusables.enterprise_migrations.specify-staging-path %}
1. Close the connection to {% data variables.location.product_location %}:
```shell
$ exit
> logout
> Connection to HOSTNAME closed.
```
1. Copy the migration archive to your computer using the [`scp`](https://acloudguru.com/blog/engineering/ssh-and-scp-howto-tips-tricks#scp) command. The archive file will be named with the Migration GUID:
```shell
scp -P 122 admin@HOSTNAME:/data/github/current/tmp/MIGRATION-GUID.tar.gz ~/Desktop
```
