We consider the problem of evolution of the many-body state of a weakly interacting system of bosons in an initially fragmented (Fock) state. We show that the state at any time can be expressed as a continuous superposition of an infinite number of Gross-Pitaevskii states. PACS:03.75.-b, 03.65.-w, 03.75.Kk
