Open Data Management > Import/Export as an Admin. The current implementation supports only IP addresses and licences; other modules do not have a general import/export contract.

Export a current file before preparing a bulk import so headers and accepted values match the running version. Validate managed-list and VLAN references, keep an application backup, then import a small sample before the full set. Review the result in the target module and Audit Logs.

Import and export are Admin-only because they can make broad changes or expose protected values.
