Conflict Resolution for Duplicate Configurations
Default Resolution Behavior
When you attempt to import a configuration, the Firewall Management Center determines whether a configuration of the same name and type already exists. When an import includes a duplicate configuration, the Firewall Management Center offers resolution options:
-  
			 Keep existing The Firewall Management Center does not import that configuration. 
-  
			 Replace existing The Firewall Management Center overwrites the current configuration with the configuration selected for import. This option is not available if the duplicate is in ancestor or descendant domain. 
-  
			 Keep newest The Firewall Management Center imports the selected configuration only if its timestamp is more recent than the timestamp on the current configuration. This option is not available if the duplicate is in ancestor or descendant domain. NoteIf you import a configuration that contains Microsoft Active Directory users and groups we strongly recommend you download all users and groups after the import to avoid issues in decryption policies, access control policies, and possibly other policies.

-  
			 Import as new The Firewall Management Center imports the selected duplicate configuration, appending a system-generated number to the name to make it unique. (You can change this name before completing the import process.) The original configuration remains unchanged. 
| Note | If you modify an imported configuration on the Firewall Management Center and later re-import that configuration to the same Firewall Management Center, you must choose which version of the configuration to keep. | 
File List Resolution Behavior
When you import an access control policy with a file policy that uses clean or custom detection file lists, and a file list presents a duplicate name conflict, the Firewall Management Center offers conflict resolution options as described, but the action taken varies as described in the table:
| Resolution Option | Resolution Behavior for the Access Control Policy | 
|---|---|
| Keep existing | Unchanged | 
| Replace existing | Imported as new; file lists are merged | 
| Import as new | Imported as new; file lists are merged | 
| Keep newest and access control policy being imported is the newest | Imported as new; file lists are merged | 
| Keep newest and existing access control policy is the newest | Unchanged |
