      When a new migration is executing, it changes migration data for all the vmim objects with the same vmi name, not only for the relevant vmim.

      For example, all pass migrations have the same uid:
      [root@e26-h06-000-r640 ~]# oc get vmim | grep fedora-8 | awk '{print $1}' | xargs -I file sh -c 'echo file; oc get vmim file -o yaml| grep -E "migrationUid"'
