+=====================================================
+A unified tool for upgrading TripleO based deploments
+=====================================================
+
+https://blueprints.launchpad.net/tripleo/+spec/tripleo-upgrade
+
+In order to avoid work duplication and automation code being out of sync with the
+official documentation we would like to create a single repository hosting the upgrade
+automation code that can be run on top of deployments done with various tools.
+
+Problem Description
+===================
+Currently automation code for TripleO upgrades is spread across several repositories
+and it is tightly coupled with the framework being used for deployment, e.g. tripleo-
+quickstart or Infrared.
+
+Proposed Change
+===============
+
+Overview
+--------
+
+Our proposal is to decouple the upgrade automation code and make it deployment tool
+agnostic. This way it could be consumed in different scenarios such as CI, automated
+or manual testing.
+
+Alternatives
+------------
+
+For the previous releases the automation code has been hosted in diffrent repositories
+such as tripleo-quickstart-extras, infrared or private repos. This is not convenient
+as they all cover basically the same workflow so we are duplicating work. We would like
+to avoid this and collaborate on a single repository.
+
+Security Impact
+---------------
+
+None.
+
+Other End User Impact
+---------------------
+
+This tool allows the users to run the TripleO upgrade in an automated fashion or
+semi-automatic by creating scripts for each upgrade step which can be later run manually
+by the user.
+
+Performance Impact
+------------------
+
+None.
+
+Other Deployer Impact
+---------------------
+
+None.
+
+Developer Impact
+----------------
+
+This tools helps developers by providing a quick way to run TripleO upgrades. This could
+be useful when reproducing and debugging reported issues.
