Key Considerations

Sandbox VMs are NOT included in backups, only the VM configuration is backed up. So, sandbox VMs must be regenerated after restoring.

Active sandbox jobs (if any) will be lost during migration.

Network connectivity must be maintained for proper service restoration.

After fresh install of Manager, the PostgreSQL database will be emptied and restored (user confirmation required).

Forcepoint recommends the original 20.04 systems should remain available as a fallback until migration is fully validated, where this is feasible.
