I'd ask myself this question: why do I need to migrate an EC2 instance to VMware?
This instance has probably some dependancies in AWS (EBS, S3, RDS...) so migrating only one component can be tricky.
So, if you are still convinced you need to do it, you have many ways to do it, but is this EC2 instance is a fresh EC2 instance or was it converted from VMware as well?
- using AWS import/export tool : VM Import/Export (works only if previously a VMware VM)
These conversion could be not 100% efficient, you have to figure out with network adapters, Re-IP, cold migration, dependancies with other components, etc...
Hope that helps
Is your problem solved?
Can you please update us and eventually share your feedback?
There is no direct migration from EC2 to VMC. If the EC2 instance was originally imported, you can use the Import / Export tool as ebernard suggested. If it was built in EC2 you will not be able to export it.
Assuming the later, if it is a Windows box you can use VMware Converter (which is recently out of support, sadly) or a similar tool within the Guest OS. If it is Linux, you can also use Converter or simply DD the boot volume to a copy either in EC2 or directly in VMC.
