Answer 1

Hi,

As per Microsoft "Migration and modernization tool migrates UEFI-based machines to Azure as Azure generation 2 VMs. If you want to migrate them to Azure generation 1 VMs, convert the boot-type to BIOS before starting replication, and then use the Migration and modernization tool to migrate to Azure"

Check this over here - https://learn.microsoft.com/en-us/azure/migrate/common-questions-server-migration

Hope this helps.
