I don't think this is realistic with respect to a typical network

replaced on some kind of schedule. I would hope that by the time
the next replacement time rolls around for the CGN hardware, it
would simply not be replaced. But this is easier to do with
stateless-in-the-core NATs.
There are multiple factors which would be relevant to the
decisions. Noel Chiappa and John Klensin commented about some of
them. The equipment replacement might be incremental. There have
been changes in the (hardware) market. Those changes can affect the
incremental replacement.
