Make Loki use schema v13 (instead of v11) with tsdb store (instead of boltdb-shipper) from tomorrow onwards:

schema_config:
  configs:
    - from: 2020-10-24
      store: boltdb-shipper
      object_store: filesystem
      schema: v11
      index:
        prefix: index_
        period: 24h
    - from: "2024-11-01"
      index:
        period: 24h
        prefix: loki_ops_index_
      object_store: filesystem
      schema: v13
      store: tsdb
