Cassandra migration from tokens to vnodes

[vidya sagar]

Hi,

I am facing an issue after adding new node to existing cluster recently. After the bootstrap for new node I am getting different token values than the configured ones.

NOTE :  I have read some where to get rid of this token ranges we can use vnodes, I am not sure how does it work.Can some one suggest please. Looking for implementing vnodes on my existing cluster setup.

cassandra version: Cassandra 3.10

Current setup (6 nodes with replication factor: 3).

Configured Token Ranges: 

-9223372036854775808

-6148914691236517206

-3074457345618258604

-2

3074457345618258600

6148914691236517202

Output of ring: 

Datacenter: datacenter1
