In our case our replication factor is more than half the number of nodes in the cluster.
Would it be possible to do the following: - Upgrade half of them - Change Thrift Port and inter-server port (is this the storage_port?) - Start them up - Upgrade clients one by one - Upgrade the the rest of the servers Or might we get some kind of data collision when still writing to the old cluster as the new storage is being used? /Daniel
