Hi @Nambi R Currently there is no official documentation or tooling available for migrating from SF to AKS.
I would need more information about your workload and how your app is written to find out more on it.
The migration could be anything from redeploy/refactor (containers or guest executables) to rewrite (Service Fabric Reliable Services and Actors) depending on your dependencies on Service Fabric.
If your app is already containerized in SF then running it in AKS shouldn't be an issue. If it is not containerized but does not use SF-specific constructs (Guest application) then that should be easy to migrate. Most difficult is, if it uses Reliable Collections/Services/Actor Framework etc. and takes a dependency on the SF SDK. That would need a re-work and there is no cookie-cutter way to address it.
Hope that helps. Let me know more about your app in the comments and I can try to get more details from the internal team.
Thanks.
