Thanks a lot for the quick reply,

Should I run the nodetool repair on all nodes before or after that?
Also, it's mentioned in the documentation that auto_bootstrap setting is applied only to non-seed nodes. Currently I specified all nodes as seeds, should I remove nodes with new IP from seeds then?

We have Cassandra cluster with 5 nodes hosted in the Amazon EC2, and  I had to restart two of them, so their IPs changed.
We use NetworkTopologyStrategy, so I simply updated IPs in the file.

Set auto_bootstrap:false in the conf file and restart the node to change IP address for a node.
