I'd be inclined to ask also what other backup is there- if you have, for example, a couple of really experienced TPs dedicated to the task, and an available greybeard line manager - should be fine in most cases, and enjoy the responsibility.
Best thing to do in any case, is have the "are you sure I'm ready for this, and what backup will I need and get" conversation with the boss.
Wasn't that what I said?
