I'm not sure I understand the relevance of this.

IB>> Imagine the situation when a major software upgrade was performed on all network controllers. The new software is significantly different from the old release. After the upgrade a serious problem was discovered. The operator wants to go back to the old software. Simple software reversion is not possible. The operator does not want to loose any of active services. So what do you do in this case? I say, do CP->MP->CP

The operating tenet is "if it aint broke don't fix it" so it'd likely
have to be a very good reason in order to make an operator move
hundreds/thousands of LSPs from CP->MP or MP->CP.  It'd also have to be
something forseeable as I can't see operators moving their LSPs from
CP->MP routinely when doing a software change.

IB>> From my remark above it should be obvious that I am not talking about routine CP->MP procedures. I am talking about "Don't stand, do something" kind of situation.
