How to Convert a Profile in ifcfg Format to Key File Format (Linux Network Interface)

Overview

The Linux network interface manages configuration with files in the ifcfg-[interface name] format (e.g., ip, netmask, gateway, etc.).
Starting from Linux version 9, the management of connection configuration has been changed to use key file format instead of ifcfg.
Accordingly, this document guides how to convert existing profiles in ifcfg format to key file format.
 
 
 

Method

Connections that read ifcfg files can be converted to key file format using the migrate command. 

file migrate

#. Existing ifcfg files are read and connections are created
[root]# nmcli -f NAME,UUID,TYPE,AUTOCONNECT,DEVICE,STATE,FILENAME connection
NAME    UUID                                  TYPE      AUTOCONNECT  DEVICE  STATE      FILENAME                                  
ens160  [interface uuid]                      ethernet  yes          ens160  activated  /etc/sysconfig/network-scripts/ifcfg-ens160 
ens192  [interface uuid]                      ethernet  yes          ens192  activated  /etc/sysconfig/network-scripts/ifcfg-ens192 

#. file migrate
[root]# nmcli connection migrate
Connection 'ens160' ([interface uuid]) successfully migrated.
Connection 'ens192' ([interface uuid]) successfully migrated.


#. Verify key file creation
[root]# ls /etc/NetworkManager/system-connections/
ens160.nmconnection  ens192.nmconnection


[root@tac1 ~]# ls /etc/sysconfig/network-scripts/
-> No files found

 

Check profile

[root]# nmcli -f NAME,UUID,TYPE,AUTOCONNECT,DEVICE,STATE,FILENAME connection
NAME    UUID                                  TYPE      AUTOCONNECT  DEVICE  STATE      FILENAME
ens160  ([interface uuid])                    ethernet  yes          ens160  activated  /etc/NetworkManager/system-connections/ens160.nmconnection 
ens192  ([interface uuid])                    ethernet  yes          ens192  activated  /etc/NetworkManager/system-connections/ens192.nmconnection
Note
It is necessary to verify the DB version that supports Linux versions 8/9.
