While I see that you have done almost all work needed for the transition, including the consumer projects, do we have to consider any breakage window when these are getting merged, as we are trying to estimate for the other task for migrating from controller APIs? Both the activities have to be done at the same window, and hence the question.
well, the overall breakage for this should not be more than half a day, so I think it should fit easily into the safety margin we need to have for the migration.
