[openstack-dev] [nova] Suggest to not deprecate os-migrations API

Hi All,

According to
, we are going to deprecate the old os-migrations API, and two new APIs:
/servers/{server uuid}/migrations and /servers/{server
uuid}/migrations/{migration id} is added.

As we can see, the newly added APIs cannot work if we don't know which
instance is migrating. If our user uses HA applications or DRS applications
such as openstack-watcher, automatic migrations can take place, we may not
know which instance is migrating. And an API like the old os-migrations
will be a really good choice to use, we can get all the current running
migrations in simply one call. So I suggest not deprecate this API.

Any thoughts?
