Thanks Paulo, We have to decommission multiple nodes from the cluster and move those nodes to other clusters. So if we have to wait for 3 days for every node then it is going to take a lot of time. If i am trying to add the decommissioned node to the other cluster it is giving me an error that cluster_name is not matching however cluster name is correct as per new cluster. So until i issue assasinate , i am not able to move forward.
