The client discards its permits for all volumes served by the peer. The server forwards its updates on the volumes to the client. The client tries to apply these updates but verifies that the versions to which the updates apply are correct. The client verifies that its update journal is adjusted so as not to be in conflict with the current state propagated by the server. When no records are left to be reintegrated on the client, the client sends its update journal to the server.
Normal operation can now resume.
