Restore Fortigate configuration to new HW model

Hello,

We are planning to move to a new HW model of our fortigate. We took a backup from current running Fortigate HW (To be replaced), and we need to smoothly recover the configuration to the new HW appliance.

Is there any tool, best practices, procedures to handle this task accurately without the need to do alot manual work?

BRs,

Ahmed Saeed
