I am trying to build a 6 node Cassandra cluster with Priam. I want to know if there is a proper bootstrap sequence to start the nodes with Priam. Also if can Priam be hooked to the existing Cassandra cluster that is running using 256 tokens and Murmer3 partitioning? Any help would be appreciated.

@haroonniazi
following properties should be set prior to starting any new cassandra cluster:
priam.create.new.token.enable = true
priam.auto.bootstrap=false

Once your cluster is created successfully or if you are adding Priam to existing Cassandra, you should make them:
priam.create.new.token.enable = false
priam.auto.bootstrap=true

For vnodes, we have a PR but is not merged yet. Currently, Priam only supports one token per instance. Regarding Murmur3 yes we do support it natively and is configurable via :
priam.partitioner = org.apache.cassandra.dht.Murmur3Partitioner
