Thanks Mark.
the p= rocedure you shared is useful. I think I have missed the nodetool rebuild c= ommand.
I am trying it out in a non-prod environment.

The num_tokens is set to 1 and initial_token is set to different values (mi= ne is a 6 node cluster with 3 in each datacenter).
Tried a rollin= g restart of the cluster. That didn't help.
Tried a cold rest= art of the cluster. That also didn't work.

I will try the nodetool rebuild and see whether any change.

Hi=C2=A0Rameez,

I have never done a migr= ation from vnodes to non-vnodes however I would imagine that the=C2=A0proce= dure=C2=A0would be the same as its counterpart. As always testing in dev sh= ould be done first.

To move from vnodes to non-vodes I would add a new datace= nter to the cluster with vnodes disabled and rebuild from your vnode cluste= r.

hello Team,

I am looking for = standard operating procedure to disable vnode in a production cluster.

This is to enable solr which doesn't work with a cassandra cluste= r having vnode enabled.

Any suggestions/

Thanks,
Rameez
