Appliance: Converting to Prefer IPv6

After the upgrade, you can convert your ESM appliance to a pure IPv6 network configuration and convert ESM to prefer using IPv6, or convert the appliance to a dual stack configuration.

Note: You will need to re-register any connectors that are registered on the appliance after you complete the conversion. The IPv4 IP address will change to a host name and the ArcSight Manager certificate will be regenerated.

To convert an appliance to use IPv6:

As user root or arcsight, stop all services:
```
/etc/init.d/arcsight_services stop all
```
As user root or arcsight, confirm that all services are stopped:
```
/etc/init.d/arcsight_services status all
```
As user root, run the network configuration script and select IPv6 or Dual Stack to change the operating system:
```
/opt/arcsight/services/bin/scripts/nw_reconfig.py
```
Reboot the system.
As user root, edit the /etc/hosts file and comment out the line that contains an IPv4 address to a hostname mapping, if present.

As user root, stop the Manager service:

/etc/init.d/arcsight_services stop manager

As user arcsight, run managersetup again:

/opt/arcsight/manager/bin/arcsight managersetup

Change the preferred IP protocol to IPv6 and change the host name to the host name of the appliance's IPv6 address.
Regenerate the ArcSight Manager certificate.
As user root, start the ArcSight Manager:
```
/etc/init.d/arcsight_services start all
```
