--------------------------------------------------------------------

So I updated my branch to grep through the logs and ignore a predefined set of 
errors just before the upgrade, as discussed offline. If there are any errors 
found which are not to be ignored, the test (any upgrade test) will fail. This 
shouldn't affect any other tests, but since the method is used by every upgrade 
test, I'll run the whole upgrade test suite to make sure nothing else breaks.

Right now just running CI on the one test:

[~krummas], where did we land with the other error message? Should it also be 
ignored?
