Not really, thats unsupported. You have to match major release and patch versions to be in compliance to use the nnmconfig export/import between two systems.
That said there's nothing really stopping you from using the import features to re-create the majority of the configurations or just setting up a throw-away instance and just upgrading offline and restore to your target server.
