I believe you meant export and not import, couple of ways
+ You can use the Ops Manager API: https://docs.pivotal.io/pivotalcf/2-2/opsman-api/
+ You can use the OM CLI: https://github.com/pivotal-cf/om
+ Check Product metadata: <opsmanager URL>/debug/product_metadata
+ Or you can check the installation YML : <opsmanager URL>/debug/files or download the installation YML from opsmanager -> settings -> export installation settings.
Hope that helps.
