Starting with PAN-OS 9.1.6, to maintain traffic
flow while using vMotion to move your VM-Series firewall on VMware
ESXi 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.
vMotion of the VM-Series firewall is supported
on vSphere 6.5, 6.7, and 7.0 if the ESXi hosts have homogeneous
CPU configuration. PAN-OS 10.0, 9.1.6, or 9.0.11 and later is required
to Use vMotion to Move the VM-Series Firewall Between Hosts installed
on vSphere 6.5 or 6.7.
