Support for migration to Azure Stack is in the backlog, but not yet prioritized. Please use the comments section and upvote the ask if you would like this functionality to light up soon.RobinK supported this idea ·RobinK commented
We need a Microsoft based solution to migrate into Azure Stack... and we need it SOON with 2008 / 2008 R2 workloads going out of support! I have customers trying to migrate2008 R2 systems from Hyper-V into Stack and there is no current solution for this other than directing them to 3rd party options. Please reassess the priority of this item.
