Exporting migration data from your enterprise	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.

2. {% data reusables.enterprise_migrations.token-generation %} on the {% data variables.product.prodname_ghe_server %} source instance.

Exporting the {% data variables.product.prodname_ghe_server %} source repositories

{% data reusables.enterprise_migrations.locking-repositories %}

{% data reusables.enterprise_installation.ssh-into-instance %} 2. 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://<em>hostname</em>/<em>username</em>/<em>reponame</em> --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 <em>PATH</em>/<em>TO</em>/<em>YOUR</em>/<em>REPOSITORY_URLS</em>.txt

3. When prompted, enter your {% data variables.product.prodname_ghe_server %} username:

Enter username authorized for migration:  admin

4. When prompted for a personal access token, enter the access token you created in "Preparing the {% data variables.product.prodname_ghe_server %} source instance":

Enter personal access token:  **************

5. 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.

> 101 models added to export
> Migration GUID: <em>example-migration-guid</em>
> Number of records in this migration:

> releases                     |  3

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.

3. If you locked the source repository, you can use the ghe-migrator target_url command to set a custom lock message on the repository page that links to the repository's new location. Pass the source repository URL, the target repository URL, and the Migration GUID from Step 5:

$ ghe-migrator target_url https://<em>hostname</em>/<em>username</em>/<em>reponame</em> https://<em>target_hostname</em>/<em>target_username</em>/<em>target_reponame</em> -g <em>MIGRATION_GUID</em>

6. 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:

$ ghe-migrator add https://<em>hostname</em>/<em>username</em>/<em>other_reponame</em> -g <em>MIGRATION_GUID</em> --lock

7. 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:

   $ ghe-migrator export -g <em>MIGRATION_GUID</em>
   > Archive saved to: /data/github/current/tmp/<em>MIGRATION_GUID</em>.tar.gz
   

   • {% data reusables.enterprise_migrations.specify-staging-path %}

8. Close the connection to {% data variables.product.product_location %}:

$ exit
> logout
> Connection to <em>hostname</em> closed.

9. Copy the migration archive to your computer using the scp command. The archive file will be named with the Migration GUID:

$ scp -P 122 admin@<em>hostname</em>:/data/github/current/tmp/<em>MIGRATION_GUID</em>.tar.gz ~/Desktop
