APPLICATION DEPENDENCY MAPPING for server migration in Azure

I am in process of migrating VMs from ESXi environment to Azure. 

Searching for an agent-less tool map the application dependencies. Thought of using Azure migrate but its agent-less version is still in preview and not GA yet.

I used Live Optics from Dell EMC but it is not giving the desired output with regards to the app dependencies(such as ports and connections).

Have also used Risc and it gives perfect results but it is a bit expensive for this project.

Any help on which tool to use would be much appreciated.

Thank You
