I do an upgrade from 1.10 to 1.11 with the helm upgrade command and see the following in the logs:

```auto

```

How can I upgrade if not with helm upgrade?

@spronin

I used

`$ helm upgrade percona-operator percona/psmdb-operator --version 1.11.0`

However, that was 4 days ago and seems to have recovered. Now I retried to reproduce and am seeing since 1 hour:

`{"level":"info","ts":1647366655.8734343,"logger":"leader","msg":"Leader pod has been deleted, waiting for garbage collection do remove the lock."}`
