You're currently on cells v1 on mitaka right? So you have some time to 
get this sorted out before getting to Rocky where the IronicHostManager 
is dropped.

I know you're just one case, but I don't know how many people are really 
running the CachingScheduler with ironic either, so it might be rare. It 
would be nice to get other operator input here, like I'm guessing CERN 
has their cells carved up so that certain cells are only serving 
baremetal requests while other cells are only VMs?

FWIW, I think we can also backport the data migration CLI to stable 
branches once we have it available so you can do your migration in let's 
say Queens before getting to Rocky.
