Both of them don't do any of that but instead deploy updates to all but 1 or 2 machines per store.Imagine if Coles or Woolies does a systemwide shutdown for an upgrade... Sorry, no groceries for you today.
So one or two normal check outs and one or two self service check outs at each store receive updates a couple of weeks behind the rest. The logic obviously behind this is that if an update is to fail or cause issues there will always be a couple of registers that will still work whilst they fix the rest.
I don't know how Velocity or something like Medibank could do the same so I think taking a whole system offline for a weekend is fair enough.
