Hi! I Use ELK 7.13.3. I was updated my cluster from 7.9.3 for fixet bug with datastream [deliting](https://github.com/elastic/elasticsearch/pull/69637).  
I have datastream which storing 7/14/30/60 days. I was change ILM policy and removed rollover step. Now I have only delete step.

```auto
PUT _ilm/policy/delete-after-7days
{
  "policy": {
    "phases": {
      "hot": {
        "min_age": "0ms",
        "actions": {
          "set_priority": {
            "priority": 100
          }
        }
      },
      "delete": {
        "min_age": "7d",
        "actions": {
          "delete": {
            "delete_searchable_snapshot": true
          }

```

and I faced with error for all my indexes which was create before last changes ILM.

```auto
Suppressed: java.lang.IllegalArgumentException: step [{\"phase\":\"hot\",\"action\":\"rollover\",\"name\":\"attempt-rollover\"}] for index [.ds-logstash-cdn-nginx-2021.07.16-2021.07.16-000001] with policy [delete-after-7days] does not exist",
"\tat org.elasticsearch.xpack.ilm.IndexLifecycleTransition.validateTransition(IndexLifecycleTransition.java:85) ~[?:?]",

```

ILM doesn't work for all old indexes and didn't clear old logs.  
Why this happen and could i fix this situation?
