Spaces are automatically enabled in {kib}. If you don’t wish to use this feature, you can disable it
by setting xpack.spaces.enabled to false in your kibana.yml configuration file.
{kib} automatically creates a default space for you. If you are upgrading from another version of {kib}, then the default space will contain all of your existing saved objects. Although you can’t delete the default space, you can customize it to your liking.
