What's wrong with just detaching the EBS volume and then attaching it to
the new node?​ Assuming you have a separate mount for your C* data (which
you probably should).

 when we replace node, we can dynamically reassign the IPs to the new node, 
reducing downtime. But we are not sure about the performance in terms of 
latency, throughput etc (we are heavy on reads).

 Any reason you think EFS would be better than EBS?

Hi,
We have a unique requirement to replace C* (3.0.x on RHEL) nodeswith a new AWS

very manual and time consuming process. We currently use EBS andexploring EFS 
as an option to speed up the process.
Does anybody have any experience running C* on EFS storage?Any 
comments/pros/cons going with this combination in Prod?

Thanks,
