RE: Can I have multiple datacenter with different versions of Cassandra

[Durity, Sean R]

No – the general answer is that you cannot stream between major versions of 
Cassandra. I would upgrade the existing ring, then add the new DC.

Subject: Can I have multiple datacenter with different versions of Cassandra

I have a need to create another datacenter and upgrade my existing Cassandra 
from 2.1.13 to Cassandra 3.0.9.

Can I do this as one step?  Create a new Cassandra ring that is version 3.0.9 
and replicate the data from an existing ring that is Cassandra 2.1.13?

After replicating to the new ring if possible them I would upgrade the old ring 
to Cassandra 3.0.9

No you can't do it in one step. Streaming between versions isn't supported

Yes, or decomission the old one and build anew after new one is operational

Can I have multiple datacenter with different versions of Cassandra

[Chuck Reynolds]

I have a need to create another datacenter and upgrade my existing Cassandra 
from 2.1.13 to Cassandra 3.0.9.

Can I do this as one step?  Create a new Cassandra ring that is version 3.0.9 
and replicate the data from an existing ring that is Cassandra 2.1.13?

After replicating to the new ring if possible them I would upgrade the old ring 
to Cassandra 3.0.9
