The text pattern upgrade is an automated process and generally includes only overwriting the old files with the ones from the new release. Here are the steps that need to be followed:

Step 1. First of all it is imperative to create a backup of your TextPattern web site. Both the files and the database should be backed up in case anything goes wrong.

Step 2. Download the latest TextPattern version package to your local computer and extract it.

Step 3. Upload the following files/folders under your TextPattern installation folder overwriting those from the old installation:

• index.php and .htaccess in the main TextPattern directory
• everything under the ‘terxtpattern’ folder (except config.php which is not included in a fresh installation package anyway).
• everything under the ‘rpc’ folder.

Step 4. When you are ready, access the administrator backend. The upgrade script will be run automatically upon login.

Step 5. It is recommended to check Diagnostics under the Admin tab for any issues. Also you can verify there that the web site is now running the latest TextPattern version.
