dblift preflight (Enterprise)
Run deployment preflight checks from a snapshot model. Preflight does everything plan does, then rehearses the migrations for real in a throwaway container — and optionally rehearses the rollback too. On Enterprise 3.4.0+, the same pending-set and placeholder flags as migrate apply; replay migrate and rehearse-rollback undo use that same subset and placeholder map.
