The information about GitLab account could be added as well. This could be obtained by using
`users API call <https://docs.gitlab.com/ee/api/users.html>`_ with `mail` as parameter. If the
user is found it will username of the user on GitLab. The final requests could look like this:

Conclusions Conclusions
----------- -----------
Conclusion for this initiative... Creating the tool for migration is possible, but with a few caveats.
We don't recommend to migrate pull requests
(:ref:`pagure2gitlab/gitlab:Importing pull requests`).
We didn't investigate the possibility of providing web interface, it's definitely possible,
but it will add much to complexity of the tool and we need to host it and deploy as well.
The main issue with the migration is that all the comments, issues are created by the user
that owns the API token, which is made to execute the API calls. This issue is explained
in :ref:`pagure2gitlab/gitlab:Importing ticker` with possible proposed solution.
The user that is using the tool will need to have permissions to create new repositories in
the GitLab group, to which the repository will be migrated.
Proposed Roadmap Proposed Roadmap
---------------- ----------------
* Step 1 - Investigate Pagure2GitLab 1. Create the tool for migration using GitLab API
* Step 2 - ??? 2. (Optional) Create a bot user for migration and share the API key with trusted people. This
* Step 3 - Profit! will help to migrate some of the projects as neutral user instead of the user, who is using
the tool.
3. Prepare the documentation for migration process.
4. Announce the migration tool is available.
