IntroductionI migrated >120 VMware virtual machines (Linux and Windows) from VMware ESXi to OpenStack. In a lab environment I also migrated from Hyper-V with these steps. Unfortunately I am not allowed to publish the script files I used for this migration, but I can publish the steps and Comm ANDs that I used to migrate the virtual machines. With the steps and commands, it should is easy-to-create scripts that does the migration automatically.Just to
