If you have customized the theme (i.e., the skin) of your Tiki, you'll want to make sure that you back up all the necessary images and stylesheets.
- Your stylesheet is located in TIKI_HOME/styles/YOUR_THEME.css.
- Graphics and additional files are located in TIKI_HOME/styles/YOUR_THEME/....
If you customized any Smarty template TPL files, be sure to back them up as well. Your customized templates are located in TIKI_HOME/templates/styles/YOUR_THEME/....
{TIP()}When possible, avoid using custom template (TPL) files, as doing so will complicate your upgrade process.{TIP}
