Need a faster way to transfer UTM to XG objects (got 20,000)

I'm migrating from a UTM to a XG firewall manually.  There is an insane amount of network, host and service objects and this is a very time-consuming process prone to human error.  I know there is a migration tool, though that will convert the whole config and in the past all I have migrated this way was broken in some form of way with more complicated setups like this one.  

Does anyone know a faster way to export these objects on the UTM and import to the XG?
