If you need to change the IP addresses for one or more instances in the system, use this procedure to manually change the IP addresses without risk of data loss.
Note: You can reuse the IP addresses of retired nodes for new nodes.

For each instance whose IP address you need to change:

  1. Move all services off of the instance. Distribute those services among all the other instances.
  2. On the instance from step 1, stop the script run using whatever tool or process you used to run it.
    For example, with systemd, run: systemctl stop hcpcs.service
  3. Remove the instance from the system.
  4. Delete the installation folder from the instance.
  5. Add the instance back to the system.
