ERAM is multichannel, which is why we do the failover between A-channel and B-channel during APL and OS CUTO. If I remember the SSMs right, we do the update on the B-channel first and once it has been approved by TechOps, A-channel is then updated.
Everything is built to provide a fallback in cause of failure, including the OS updates when they come in.
