+NetworkManager was built to automatically migrate connection profiles in
+this directory to equivalent ones in keyfile format in directory
+/etc/NetworkManager/system-connections.
+
+You can check whether the migration is enabled via:
+
+ $ NetworkManager --print-config | grep migrate-ifcfg-rh
+
+In case it is enabled, all files in this directory are migrated at startup.
+
+To inspect where your connection files are currently stored use:
+
+ $ nmcli -f name,uuid,filename connection
+
+Background
+==========
+
+The ifcfg format is deprecated and will be removed in future releases. For
+more information see:
+
+https://lists.freedesktop.org/archives/networkmanager/2023-May/000103.html
+
+Connection profiles in keyfile format have many benefits. For example, this
+format is INI file-based and can easily be parsed and generated.
+
+Each section in NetworkManager keyfiles corresponds to a NetworkManager
+setting name as described in the nm-settings(5) and nm-settings-keyfile(5)
+man pages. Each key-value pair in a section is one of the properties listed
+in the settings specification of the man page.
+
+How to keep using ifcfg
+=======================
+
+If you want to keep using connection profiles in ifcfg format, you need to:
+
+ - disable the automatic migration to keyfile by setting
+   "migrate-ifcfg-rh=false" in the [main] section of NetworkManager
+   configuration;
+
+ - optionally, set "plugins=ifcfg-rh" in the [main] section of
+   NetworkManager configuration so that new profiles are created in ifcfg
+   format.
+
+At this point, you can migrate all your files back via
+
+  nmcli connection migrate --plugin ifcfg-rh
+
+Or, if you prefer to migrate only specific connections:
+
+  nmcli connection migrate --plugin ifcfg-rh <profile_name|UUID>
+
+Note that some connection types are not supported by the ifcfg plugin.
+
+Interface renaming
+==================
+
+Connection profiles stored in ifcfg-rh format support the renaming of
+interfaces via udev. This is done via a helper tool
+/usr/lib/udev/rename_device that is invoked by udev to parse the files
+in /etc/sysconfig/network-scripts; when the HWADDR and DEVICE
+variables are set, the interface that matches the MAC address in
+HWADDR is renamed to the name specified in DEVICE.
+
+Connections in keyfile format don't provide the same integration with
+udev. The renaming of interfaces must be configured directly in udev,
+for example by creating a file:
+
+  /etc/systemd/network/70-rename.link
+
+with content:
+
+  [Match]
+  MACAddress=00:11:22:33:44:56
+
+  [Link]
+  Name=ethernet1
+
+Alternatively, a udev rule can also be used, such as:
+
+  /etc/udev/rules.d/70-interface-names.rules
+
+with content:
+
+  SUBSYSTEM=="net",ACTION=="add",ATTR{address}=="00:11:22:33:44:56",ATTR{type}=="1",NAME="ethernet1"
