Hosts are exported with many related objects and object relations.
Host export contains:
When a host is imported and updated, it can only be linked to additional templates and never be unlinked from any.
To export hosts, do the following:

Selected hosts are exported to a local XML file with default name zabbix_export_hosts.xml.
To import hosts, do the following:

All mandatory input fields are marked with a red asterisk.
A success or failure message of the import will be displayed in the frontend.
Import rules:
| Rule | Description | 
|---|---|
| Update existing | Existing elements will be updated with data taken from the import file. Otherwise they will not be updated. | 
| Create new | The import will add new elements using data from the import file. Otherwise it will not add them. |
