Creating a snapshot of VM instances
In VM environments, it is recommended to stop the VM instance and take a snapshot or clone of the VM instance before the upgrade. If there are issues with the upgrade, you can revert to the VM snapshot or clone.

Avoid taking snapshots when applications in the virtual machine are communicating with other computers. |
If you are upgrading a FortiAnalyzer VM, make sure your VM partition has more than 512MB (1024MB or more recommended) and your VM server is up to date.
