As suggested, we did do removetoken, set autobootstrap true, initial token and start. Now the new nodes are in the Boostrapping state for a while, but nothing seem to be happening at all.
Any idea? Thanks.

Once you have started a node with auto-bootstrap=false, changing the configuration file no longer works. The nodes are bootstrapped and joined to the cluster. Yes. you want to decommission or removetoken the new nodes. Set auto-bootstrap to true, set an initialtoken and start them.
