+Migrating to Storyboard
+-----------------------
+If your project is thinking about migrating to Storyboard
+or has recently migrated to Storyboard, the following will
+help you get started.
+
+Planning to Migrate
+-------------------
+So you want to migrate...
+
+- Talk to the storyboard team to see if your project is ready i.e.
+  isn't heavily dependent on other projects, migrates into a test
+  environment cleanly, etc. The #storyboard channel is a good place
+  to start this conversation. We have `regular meetings
+  <http://eavesdrop.openstack.org/#StoryBoard_Meeting>`_ for you to
+  drop into as well
+- Once it's been decided that you can migrate cleanly, pick a date
+  to make the change and in the interim, try to close as many bugs
+  as possible
+
+
+The Migration Process
+---------------------
+
+- One patch needs to be pushed to the project-config repo to modify
+  `projects.yaml <https://github.com/openstack-infra/project-config/blob/master/gerrit/projects.yaml#L255-L256>`_
+  to update 'use-storyboard' to True for each of your projects in that file
+- A representative from infra runs the migration scripts
+
+Recently Migrated
+-----------------
+
+- Communicate to your project, your users and operators that bugs will now
+  be filed in your `storyboard project <https://storyboard.openstack.org/>`_
+  rather than launchpad project
+- Lock your launchpad project so that users and operators can't file
+  bugs there. In the 'Change Details' section you should update information
+  about where to file bugs now, then go to the 'Bugs' section and set the
+  'bugs are tracked' radio button to the 'somewhere else' option.
+
+  NOTE: Launchpad does not close open bugs or note the new location that
+  people should make comments and updates at which is why it is important
+  to communicate to users, operators, and contributors that you've migrated 
+
+Q & A
+-----
+
+- Is there integration with gerrit? Yes. `Details here.
+  <https://docs.openstack.org/infra/manual/developers.html#development-workflow>`_
+- What happens to bug links? Bug numbers are the story numbers and are
+  used in the url for the story
+- What happens to blueprints? They are not migrated because they
+  are a construct tied to Launchpad. They can be optionally migrated, but
+  it's not supported by default
+- How do I close a task? Change the status from 'Todo' to 'merged'.
+  The state of the story overall is derived from each of the tasks.
+  While tasks can be complete, the story may not be done until all
+  tasks are marked as 'merged' or 'invalid'. See the gerrit integration
+  link above for more details
+- Are there tags? Yes, anyone can add any tags to stories
+- Will I be able to write scripts for it? Yes, there is a
+  `REST API <https://docs.openstack.org/infra/storyboard/webapi/v1.html>`_
+- Why are we using Storyboard? It was designed for the OpenStack
+  use case and the ability to manage cross project efforts. It
+  is managed by OpenStack and so it can be fixed and changed
+  quickly.
