Movement of buckets in an indexer cluster

Hello All, today someone asked me a question about bucket movement in an indexer cluster. Lets say i have 5 indexer in a cluster and i have an index called operations. My question is as follows. Assuming that the replication is happening properly, When my hot bucket rolls to warm, What happens to the rest of the buckets that are replicated on the indexers? When my warm bucket rolls to cold, What happens to the rest of the buckets that are replicated on the indexers? When my cold bucket rolls to frozen, What happens to the rest of the buckets that are replicated on the indexers? i read a lot of articles about bucket movement but i cannot find a proper explanation for this. any help in shedding some light on this topic will be highly appreciated. Thanks
