We want to change our cluster's nodes IP addresses.
We run ES in a docker container (using host network) and we mount the local disk to the container.
My question are:
Is it possible to do this via rolling restarts ?
Will the data be preserved on the node ?
If we can do rolling restart, we will have mixed networks (private + public) until we migrate all nodes. Can this be a problem ?
If rolling restarts are not possible, it is acceptable to stop the cluster, change the server IP's and start again. Will the data be still OK after that ?
Thank you in advance.
