Changes to the OS only affect new nodes and reinstalled nodes, not existing nodes.
Nodes in the same cluster can use different OS versions without affecting cluster functionality.
One script does not suit all operating systems. After configuring a node with a script, run a test to make sure it is compatible with the operating system.
If you want to use custom images, submit a ticket for further assistance.
