Upgrading Warewulf

New versions of Warewulf might introduce changes to warewulf.conf and nodes.conf. The wwctl upgrade command can help ease the transition between versions.

Note

wwctl upgrade will back up any files before it changes them (to <name>-old) but it is good practice to back up your configuration manually.

# wwctl upgrade config
# wwctl upgrade nodes --add-defaults --replace-overlays

Both upgrade commands support specifying --output-path=- to print the upgraded configuration file to standard out for inspection before replacing the configuration files.
