Beginning with PAN-OS 10.0.1, the VM-Series firewall on ESXi and NSX-T support VMotion. To maintain traffic flow while using vMotion to move your VM-Series firewall on VMware ESXi and VM-Series firewall on VMware NSX-T (N-S and E-W) between ESXi hosts, you must use the PAN-OS CLI to pause the internal heartbeat monitoring of the VM-Series firewall during vMotion. You can specify the amount of time, in minutes, that heartbeat monitoring is paused. Heartbeat monitoring can be paused for up to 60 minutes. When the pause interval expires or you deliberately end the pause interval, heartbeat monitoring resumes.
