I need to migrate my master node of my cluster (1 master, 3 workers). The master node does not have any data from container volumes. All persistent volume data are stored in the worker nodes. The master does no run any container (NoExecute taint).
Can I do it in a way that when the current workers connect to the new master nothing changes (basically just the master IP address)?
I think I just need to know where the master node keeps its state data. So I can copy it to the new master's disk and the new master has the information about all running resources.
