Changing Cluster CIDR in RKE1

Support
1

Hi Team,

I have a running cluster of RKE and RKE2 with the default CIDR 10.42.0.0, With a recent migration of application servers, The servers has been assigned with 10.42.x.x IP and now it is having a conflict with communication, The only option left is to change the cluster CIDR without any data loss or user workloads.

Please suggest recommended approach for this.

Thanks in advance.
