Migrating projects between version control repositories

If your organization has changed Git hosting services, and you therefore need to migrate projects from one supported version control repository to another, we recommend you follow this high-level process:

  1. Perform pre-migration setup.
  2. Run the project migration script.
  3. Perform post migration cleanup.
  4. Adding collaborators.


  • Update the Anaconda Enterprise config map with the information required to connect to the external version control repository.
  • To run the project migration script, you’ll need Administrator access to a command line tool that can run bash or Python scripts on the master node of the Anaconda Enterprise cluster.
  • Ensure a recent version of git is installed on the master node
  • You’ll also need the origin Git host token/password, and destination Git host token/password.

Pre-migration setup

  1. If you haven’t already done so, on the master node, change to the directory of the unpacked Anaconda Enterprise installer and install the bootstrap conda environment:

    bash conda-bootstrap.sh
  2. After the environment is finished installing, you may need to log out and log back in to activate the conda environment.

  3. Temporarily disable reverse proxy authentication by adding the following key-value pair to the git section (outside of the storage section in the config map) of the anaconda-enterprise-anaconda-platform.yml file used to configure the platform to use an external version control repository:

    reverse-proxy-auth: false

    This should look similar to the following:

  4. Run the following command to restart the associated pod on the master node:

    kubectl delete pod -l 'app=ap-git-storage'
  5. Create a user mappings file that maps Anaconda Enterprise user IDs to Git user IDs. This is a colon-separated text file where the first field is the AE user name, and the second field is the corresponding Git user name. For example:



    If you intend on migrating to or from a Bitbucket repository, you must use your Bitbucket account ID instead of your Bitbucket username in the user mappings file.

Using the migration tool


Using the migration tool with https instead of http for the internal storage may result in an SSL error.

The migration tool is a Python script, migrate_projects.py, found in the AE5 installation tarball. It can be used in the following ways:

usage: migrate_projects.py [-h] [--parallel PARALLEL] [--log-file LOG_FILE]
                      [--force-migrate] [--scratch-dir SCRATCH_DIR]
                      --postgres-host POSTGRES_HOST
                      [--postgres-user POSTGRES_USER]
                      [--postgres-passwd POSTGRES_PASSWD]
                      [--origin-api-type {internal,bitbucket-v1-api,bitbucket-v2-api,github-v3-api,gitlab-v4-api}]
                      --origin-api-url ORIGIN_API_URL
                      [--origin-username ORIGIN_USERNAME]
                      [--origin-token ORIGIN_TOKEN]
                      [--origin-organization ORIGIN_ORGANIZATION]
                      [--dest-api-type {internal,bitbucket-v1-api,bitbucket-v2-api,github-v3-api,gitlab-v4-api}]
                      --dest-api-url DEST_API_URL
                      [--dest-username DEST_USERNAME]
                      [--dest-token DEST_TOKEN]
                      [--dest-organization DEST_ORGANIZATION]
                      --dest-user-mappings DEST_USER_MAPPINGS

optional arguments:
-h, --help            show this help message and exit
--parallel PARALLEL   Number of parallel migration jobs to spawn
--log-file LOG_FILE   Path prefix to log directory, suffixed with a
                    timestamp, e.g. migrate-projects-
--force-migrate       Forces migration by replacing local and destination
--scratch-dir SCRATCH_DIR
                    The scratch directory for cloning project repositories
--postgres-host POSTGRES_HOST
                    Hostname of AE5 Postgres DB
--postgres-user POSTGRES_USER
                    Username of AE5 postgres DB
--postgres-passwd POSTGRES_PASSWD
                    Password of AE5 postgres DB
--origin-api-type {internal,bitbucket-v1-api,bitbucket-v2-api,github-v3-api,gitlab-v4-api}
                    Origin git host API type
--origin-api-url ORIGIN_API_URL
                    Origin git host API URL
--origin-username ORIGIN_USERNAME
                    Origin git host username
--origin-token ORIGIN_TOKEN
                    Origin git host auth token
--origin-organization ORIGIN_ORGANIZATION
                    Origin git host organization
--dest-api-type {internal,bitbucket-v1-api,bitbucket-v2-api,github-v3-api,gitlab-v4-api}
                    Destination git host API type
--dest-api-url DEST_API_URL
                    Destination git host API URL
--dest-username DEST_USERNAME
                    Destination git host username
--dest-token DEST_TOKEN
                    Destination git host auth token
--dest-organization DEST_ORGANIZATION
                    Destination git host organization
--dest-user-mappings DEST_USER_MAPPINGS
                    Colon-separated AE-to-git-host mappings file, e.g. ae-

For example, the tool can be used in the following way:

python migrate_projects.py \
  --postgres-host localhost --origin-api-url http://localhost:8443/ \
  --origin-username root --dest-api-type gitlab-v4-api \
  --dest-api-url https://mbrock-gitlab.anacondaenterprise.com/ \
  --dest-username root --dest-organization demo --dest-user-mappings \
  user-mappings-gitea-to-gitlab.txt --force-migrate --parallel 4

To ensure tokens are not visible in bash history, they can be omitted and can be entered via stdin when running the script.


The postgres password can be left blank. When migrating from Anaconda Enterprise, the origin-token can be left blank. When migrating to Anaconda Enterprise, the dest-token can be left blank.

Post-migration cleanup

After the script finishes migrating the projects, re-enable reverse proxy authentication by editing the key-value pair you previously added to the git section of the anaconda-enterprise-anaconda-platform.yml file, so it looks like the following:

reverse-proxy-auth: true


If you do not re-enable reverse proxy authentication, Anaconda Enterprise will not work.

To verify that the new repository is being used by Anaconda Enterprise, edit an existing project and commit your changes to it.

Adding collaborators

If you’ve migrated to https://github.com, whenever a user is added to a project as a collaborator, they’ll be sent an invitation to collaborate via email. They’ll need to accept this invitation to be able to commit changes to the repository associated with the project. This does not apply to Github Enterprise.
