Which HCX migration method would be the most appropriate to use in order to migrate both business-critical VMs and dev-test VMs?

  A. HCX Bulk Migration for migrating business-critical VMs and HCX vMotion for non-critical dev-test VMs
  B. HCX vMotion for migrating business-critical VMs, and Cold Migrations for non-critical dev-test VMs
  C. Cold Migration for migrating both business-critical and non-critical dev-test VMs
  D. HCX Bulk Migration for migrating the business-critical VMs, and Cold Migrations for non- critical dev-test VMs
