[Bug 1755475] Re: Cold migration with destination host

[Corey Bryant]

Yes upgrading from Ocata to Pike is supported. The process might be
different depending on how you're deployed. If your deployment was
automated using a project such as juju, ansible, kolla, puppet, the
process may be different for each of those and you'll want to read the
documentation from those projects to understand how to upgrade. If you
deployed by hand I'd check the upstream documentation
https://docs.openstack.org or try asking in #openstack-doc IRC channel
on freenode.

Title:
  Cold migration with destination host

Status in nova package in Ubuntu:
  Invalid

Bug description:
  I need OpenStack to support cold migrations by choosing the
  destination host.

  The version of my OpenStack is Ocata with the API Nova version 2.1.

  According to official documentation the API that supports such
  migrations is 2.56 (https://developer.openstack.org/api-ref/compute
  /#migrate-server-migrate-action)

  Is there any way to update the API only?

  Is there a need to do any extra configuration on the new one for this
  type of migration to work? live migration is already working ...
