@Arjun Cloud Associate Sorry for delay in response to your query.
It’s not clear what you’re asking with this question: “What will be the compute capacity”.
Azure Migrate has the assessment engine that will give you estimated targets for CPU, Memory, and Storage equivalent in Azure.
As for the third question about availability zones, per this FAQ page it is not supported yet.
As a workaround, you can use Azure Site Recovery (ASR) to migrate from non-Zone into Zone-specific configurations (within the same region), after you have migrated the VMs into Azure.
