# Convert old themes to the new format > This is now invalid, old theme support has been removed and will be part of a separate tool. **Rofi** 1.4 can still read in and convert the old theme format. To read the old format, convert it, and dump it into a new file run: ```bash rofi -config {old theme} -dump-theme > new_theme.rasi ``` This gives a very basic theme, with the colors from the old theme. You can preview the theme using: ```bash rofi -theme new_theme.rasi -show run ```
