Hello!
Recently I upgraded from 6.7 to 7.2 (non-OSS free edition, upgraded with entire cluster restart). Previously I've been using ILM policies and they were working like a charm since release. But after I upgraded, they partly stopped. Indices with short lifetime (I mean, created already on 7.2) are rotating, while old indices, created under 6.7 or older are ignoring policies. If I search indices with Kibana, all of them are covered by ILM, while not rotating.
For example, this is ILM explain output of the index that should've been rotated (policy - delete after 90 days):
```
{
"indices" : {
"shrink-openapi-2019.04.28" : {
"index" : "shrink-openapi-2019.04.28",
"managed" : true,
"policy" : "openapi",
"lifecycle_date_millis" : 1556409515689,
"phase" : "cold",
"phase_time_millis" : 1561593545477,
"action" : "complete",
"action_time_millis" : 1561593572636,
"step" : "complete",
"step_time_millis" : 1561593572636,
"phase_execution" : {
"policy" : "openapi",
"phase_definition" : {
"min_age" : "60d",
"actions" : {
"freeze" : { },
"set_priority" : {
"priority" : 30
}
}
},
"version" : 6,
"modified_date_in_millis" : 1558542408695
}
}
}
}
```
And here is policy:
```
{
"openapi" : {
"version" : 1,
"modified_date" : "2019-07-17T12:08:26.644Z",
"policy" : {
"phases" : {
"warm" : {
"min_age" : "30d",
"actions" : {
"forcemerge" : {
"max_num_segments" : 25
},
"set_priority" : {
"priority" : 50
},
"shrink" : {
"number_of_shards" : 1
}
}
},
"cold" : {
"min_age" : "60d",
"actions" : {
"freeze" : { },
"set_priority" : {
"priority" : 0
}
}
},
"hot" : {
"min_age" : "0ms",
"actions" : {
"set_priority" : {
"priority" : 100
}
}
},
"delete" : {
"min_age" : "90d",
"actions" : {
"delete" : { }
}
}
}
}
}
}
```
Is there any way to diagnose my problem and fix it? Sure, there is curator available, but I think it's not the right solution...

Solved. The reason was that I had one index linked to non-existing policy. After I removed policy from that index, everything works fine.
