Hi Nitan, I think it would be simpler to take one node down at a time and replace it by bringing the new node up after linux upgrade, doing same cassandra setup, using replace_address option and setting autobootstrap=false ( as data is already there). No downtime as it would be a rolling upgrade. No streaming as same tokens would work. If you have latest C*, use replace_address_first_boot. If option not available, use replace_address and make sure you remove it once new node is up. Try it and let us know if it works for you. ThanksAnuj

You can't do that because it requires streaming between versions, which isn't supported. You need to take a node down, upgrade the C* version, then start it back up.
