How to change POD_CIDR range after installation?

Praveen Viswanath:
Hi Team , Is there a way to change POD_CIDR range after installation . I had previously installed using POD_CIDR=“172.16.0.0/16”. Now need to change it to “172.15.0.0/16”. Please can you tell me the method to change it

there may be many ways… this is one option: drain, delete, and re-init the node.
