Are there compelling reasons that these systems can't be broken into parts and then each part gets gradually replaced in turn?
Clearly some aspects will be tied together, so for them it's all or nothing.
It does feel like these companies have got to bite the bullet and get started, otherwise that facade of being conservative will fall, to reveal recklessness.
