Upgrading an existing Tiki site is similar to installing a new site. In fact, you'll use the same Tiki Installer (tiki-install.php) used to install Tiki.
Upgrading is essentially a three-step process:
- Back up your existing site information.
- Unpack/copy the Tiki archive/files to your web server
- Run the Tiki Installer, selecting the Upgrade option.
