i3‐migrate‐config‐to‐v4 − migrates your i3 config file

mv ~/.i3/config ~/.i3/old.config
i3−migrate−config−to−v4 ~/.i3/old.config > ~/.i3/config

i3−migrate−config−to−v4 is a Perl script which migrates your
old (< version 4) configuration files to a version 4 config
file. The most significant changes are the new commands (see
the release notes).

This script will automatically be run by i3 when it detects
an old config file. Please migrate your config file as soon
as possible. We plan to include this script in all i3
release until 2012−08−01. Afterwards, old config files will
no longer be supported.
