So our KeyCloak operator automatic updated to v25.0.0, and hereafter our deployed instance container stopped working.

```auto

    "timestamp": "2024-06-10T15:38:07.803176109Z",
    "sequence": 9868,
    "loggerClassName": "org.jboss.logging.Logger",
    "loggerName": "org.keycloak.quarkus.runtime.cli.ExecutionExceptionHandler",
    "level": "ERROR",
    "message": "Error details:",
    "threadName": "main",
    "threadId": 1,
    "mdc": {},
    "ndc": "",
    "hostName": "keycloak-prod-0",
    "processName": "QuarkusEntryPoint",
    "processId": 1,
    "exception": {
        "refId": 1,
        "exceptionType": "org.keycloak.models.ModelException",
        "message": "Incorrect state of migration. You are trying to run server version '25.0.0' against a database which was migrated to snapshot version '999.0.0'.

        "frames": [
            {
                "class": "org.keycloak.storage.datastore.DefaultMigrationManager",
                "method": "migrate",
                "line": 151
            },
            <snip>
        ]
    }
}

```

How can I solve this migration errors in DB? It gues it was running v24 before.

Also, when the container starts, it have this warning.

```auto

I solved this by login to the postgresql database and deleted the 999 version migration from migration\_model.
