Zusammenfassung:	Techniques are disclosed for live migrating an existing connection between a local gateway in a virtualized computing environment and a remote gateway. The existing IKE and IPSec connection are frozen. MMSA and QMSA data for the IKE and IPSec connection are saved. Data for the existing IKE and IPSec connection is cleared at the local gateway without sending a message to the remote gateway. The saved MMSA and QMSA data are transferred to a new local gateway. Using the saved MMSA and QMSA data, a state for the existing IKE and IPSec connection is reconstructed at the new local gateway. The existing IKE and IPSec connection is enabled.
