    - Have the changes verified by a 2nd pair of eyes (Aaron)
    - Apply the changes in several commits (about 1 per action listed on bug 843628)

* rollback plan / rollback point (at which point will you determine to roll back)
    if any outage:
    - rollback the previous commit: 3min outage max for the specific changes
    - troubleshot (max 15min)
    - If issues found, apply the change again, otherwise skip this change and investigate more after the window

* notification mechanisms
    oncall + netops (+ larger announcement as it will be part of a larger maintenance)
