When master node shut down, VIP and OVNDB Master will go to other node. On the node that will become the master, if the VIP starts upgrading earlier than OVNDB promote, the ovsdb process in backup state will reconnects to the VIP at its own node, and clears the data in the local database in RPL_S_SEMEME_REQUESTED state. So the VIP started must be after OVNDB promote.
