A new VMware Fling from Chris Halstead is available. With that you can migrate all Applications and Entitlements from one vIDM instance to another (on-premise and SaaS).
The Export and Import use the standard built in APIs of VMware Identity Manager (vIDM). The Entitlements will be saved in an XML-File and will be imported from there in the new vIDM instance.
Take a look here for a short Demo: vIDM Migration Tool
