GitLab to Atlassian

This repository contains two scripts (dump_gitlab_json.py and gitlab_to_stash.py) that export issues and code from GitLab to JIRA and Stash respectively. Each script is described in more detail below.

Dumping JIRA-compatible issue JSON from GitLab

This script attempts to export all of the issues (and the users associated with them) from GitLab to JIRA. I wrote it in a few hours, but it got the job done. I'm posting it on GitHub since other people may also find it useful.

Usage

usage: dump_gitlab_json.py [-h] [-d DATE_FILTER] [-e] [-i IGNORE_LIST]
                           [-p PASSWORD] [-P PAGE_SIZE] [-s] [-t TOKEN]
                           [-u USERNAME] [-v] [--version]
                           gitlab_url

Export all users/issues from GitLab to JIRA JSON format.

positional arguments:
  gitlab_url            The full URL to your GitLab instance.

optional arguments:
  -h, --help            show this help message and exit
  -d DATE_FILTER, --date_filter DATE_FILTER
                        Only include issues, notes, etc. created after the
                        specified date. Expected format is YYYY-MM-DD
                        (default: 1970-01-01)
  -e, --include_empty   Include projects in output that do not have any
                        issues. (default: False)
  -i IGNORE_LIST, --ignore_list IGNORE_LIST
                        List of project names to exclude from dump. (default:
                        None)
  -p PASSWORD, --password PASSWORD
                        The password to use to authenticate if token is not
                        specified. If password and token are both unspecified,
                        you will be prompted to enter a password. (default:
                        None)
  -P PAGE_SIZE, --page_size PAGE_SIZE
                        When retrieving result from GitLab, how many results
                        should be included in a given page?. (default: 20)
  -s, --verify_ssl      Enable SSL certificate verification (default: False)
  -t TOKEN, --token TOKEN
                        The private GitLab API token to use for
                        authentication. Either this or username and password
                        must be set. (default: None)
  -u USERNAME, --username USERNAME
                        The username to use for authentication, if token is
                        unspecified. (default: None)
  -v, --verbose         Print more status information. For every additional
                        time this flag is specified, output gets more verbose.
                        (default: 0)
  --version             show program's version number and exit

Exporting GitLab projects and repositories to Stash

gitlab_to_stash.py clones all projects from GitLab and recreates them on Stash. It attempts to replicate the GitLab's project/namespace hierarchy.

Usage

usage: gitlab_to_stash.py [-h] [-p PASSWORD] [-P PAGE_SIZE] [-s] [-S]
                          [-t TOKEN] [-u USERNAME] [-v] [--version]
                          gitlab_url stash_url

Transfer all projects/repositories from GitLab to Stash. Note: This script
assumes you have your SSH key registered with both GitLab and Stash.

positional arguments:
  gitlab_url            The full URL to your GitLab instance.
  stash_url             The full URL to your Stash instance.

                        you will be prompted to enter a password. (default:
                        None)
  -P PAGE_SIZE, --page_size PAGE_SIZE
                        When retrieving result from GitLab, how many results
                        should be included in a given page?. (default: 20)
  -s, --verify_ssl      Enable SSL certificate verification (default: False)
  -S, --skip_existing   Do not update existing repositories and just skip
                        them. (default: False)
  -t TOKEN, --token TOKEN
                        The private GitLab API token to use for
