Removing Seed node from Datastax datacenter

Question

I have 6 nodes in our data center of which 3 node also act as seed nodes.I was planning to remove 3 nodes from rack2 and also reduce seed node count to two. With "nodetool decommission" we can remove nodes but is there any extra steps involve in removing seed nodes.
