Nothing new, but you can certainly use SAS Management Console to export packages from your 9.3 environment, and import them using SAS Management Console in your 9.4 environment. This would cover metadata.
If you're looking to migrate your entire SAS 9.3 environment to SAS 9.4, you'll want to use the SAS Migration Utility on the 9.3 side to create a complete migration package which includes all your configuration information, and then read it in using the SAS Deployment Wizard on the 9.4 side.
For general information/pointers on migrating SAS environments, consult the Migration Focus Area at:
