Hello,
Surely you get *some* downtime to this application (assuming it's
read-write) when you perform the switchover?
In terms of the state of the binaries and catbundle, your method is
equivalent to a rac rolling install - you end up running one node with the
patched software but without catbundle being applied immediately.
