# Migrating to new hardware
 
 
## Change one or more NICs
 
Open a CLI and start the setup-wizard.
 
```text
`setup`
setup
```
 
First you have to remove the obsolete NICs before you are able to assign the new ones.
 
 
## Change the mainboard
 
If you change you mainboard the sensor-chips will usually change too. So it is necessary to rescan for sensor-chips and remove obsolete rrd-files.
 
 
### Rescan for sensors
 
```text
/usr/sbin/sensors-detect
```
 
`/usr/sbin/sensors-detect`
Follow the dialogue to generate a new configfile (locate at `/etc/sysconfig/lm_sensors`).
 
Follow the dialogue to generate a new configfile (**/etc/sysconfig/lm_sensors**).
To remove the obsolete sensors from the list of selectable sensors on the webif you have to remove the obsolete folders (sensors-*) from `/var/log/rrd/collectd/localhost`.
 
To remove the obsolete sensors from the list of selectable sensors on the webif you have to remove the obsolete folders (sensors-*) from "**/var/log/rrd/collectd/localhost**" .
**Important!** You must stop `collectd` before you change the rrd data, see below.

Stop collectd:
 
```text
`/etc/init.d/collectd stop`
/etc/init.d/collectd stop
```
 
You have to remove the "old" rrd-files within the folders "**/var/log/rrd**" and **subfolders**.

Now you have to start the "collectd"
Now you have to start the `collectd`.
 
```text

Finally a reboot is recommend.
