Comment 6 for bug 1945439

@Bogdan - especially the undercloud upgrade we need to keep running.
For the FFU case, the undercloud is upgraded through 3 consecutive versions, i.e. we run undercloud upgrade 3 times. So the point to point upgrade needs to keep working in this case especially. Unless that has completely changed ;) but I'd ask the upgrades team to sign off on it - I think there will just have to be some workaround for this upgrade in particular where the runtime changes.
