What’s New in FortiManager v5.0 : FortiManager v5.0 Patch Release 6 : Import improvements
 
Import improvements
The following improvements have been made to the import operation:
Auto resynchronization when tunnel re-up: After changes are made to a FortiGate, when the tunnel comes back online, the changes are auto-synchronized to FortiManager. The device manager database is always in sync with the FortiGate and the out-of-sync condition has been removed.
Detect FortiGate changes that impact policy & objects: FortiManager now is able to detect when the settings were changed on the FortiGate and synchronized back to the related policy and object settings. This allows you to know when the policy package is out-of-sync with what is installed on the FortiGate. You can either re-apply the changes or modify the policy package.
Warning when overwrite an existing policy package: FortiManager now displays a warning dialog box allowing you to decide to either overwrite the policy package, cancel the import, or import the policy package under a different name.
