If you are running virtual machines today, you're already using a cloud-based technology, although we do not call it cloud today. Basically, this is the idea of a private cloud. If you are running Azure Pack today, you are quite near Azure Stack from the processes point of view but not the technology part. There is a solution called connectors for Azure Pack that lets you have one portal UI for both cloud solutions. This means that the customer can manage everything out of the Azure Stack Portal, although services run in Azure Pack as a legacy solution.
Basically, there is no real migration path within Azure Stack. But the way to solve this is quite easy, because you could use every tool that you can use to migrate services to Azure.
The Azure Website Migration Assistant will provide a high-level readiness assessment for existing websites. This report outlines sites that are ready to move and elements that may need changes, and it highlights unsupported features. If everything is prepared properly, the tool creates any website and the associated database automatically and synchronizes the content.

For virtual machines, there are two tools available:
Virtual Machines Readiness Assessment
Virtual Machines Optimization Assessment
The Virtual Machines Readiness Assessment tool will automatically inspect your environment and provide you with a checklist and detailed report on steps for migrating the environment to the cloud.

If you run the tool, you will get an output like this:
The Virtual Machines Optimization Assessment tool will at first start with a questionnaire and ask several questions about your deployment. Then, it will create an automated data collection and analysis of your Azure VMs. It generates a custom report with ten prioritized recommendations across six focus areas. These areas are security and compliance, performance and scalability, and availability and business continuity.
