IP Address or Hostname Change
If you have installed FOXMAN‑UN already but need to change the IP address and/or the hostname of your core machine, proceed as described below.
For an IP address or hostname change,
Proceed as follows: 
1. Perform a FOXMAN‑UN database backup, e.g., by using the manual backup provided in the NEM Remote Admin Tool (RAT).
When using the manual backup from the NEM RAT the backup is stored in /opt/nem/var/backups/manual
The FOXMAN‑UN license is stored in /opt/nem/etc
2. Copy the database backup, the FOXMAN‑UN license and any other licenses you may have stored in a folder under /opt/nem to a safe place, preferably outside /opt/nem.
If you have an active Main/Standby redundancy in operation, a switch-over to the standby server may be considered now. For details see the documentation of the Main/Standby feature.
3. Change the IP address and/or hostname of the machine in accordance with the RHEL manual, as required.
4. Execute the script /opt/nem/bin/private/reconfigure_nem
This will show the following output and prompt:
