This document contains information for an outdated version and may not be maintained any more. If some of your projects still use this version, consider upgrading as soon as possible.
Usually an update or upgrade your SilverStripe installation just means overwriting files and updating your database-schema. Please see your upgrade notes and changelogs.
Never update a website on the live server without trying it on a development copy first.
- Check if any modules (e.g. blog or forum) in your installation are compatible and need to be upgraded as well
- Backup your database
- Backup your website
- Download the new release and uncompress it to a temporary folder
- Leave custom folders like mysite or themes in place.
- Identify system folders in your webroot (
sapphireand any additional modules).
- Delete existing system folders (or move them outside of your webroot)
Extract and replace system folders from your download (Deleting instead of "copying over" existing folders ensures that files removed from the new SilverStripe release are not persisting in your installation)
- Visit http://yoursite.com/dev/build/?flush=1 to rebuild the website Database
- Check if you need to adapt your code to changed APIs
Check if you need to adapt your code to changed CSS/HTML/JS
- See common-problems for a list of likely mistakes that could happen during an upgrade.
How easy will it be to update my project? It's a fair question, and sometimes a difficult one to answer. This page is intended to help you work out how hard it will be to upgrade your site.
- If you've made custom branches of the core, or of a module, it's going to be harder to upgrade.
- The more custom features you have, the harder it will be to upgrade. You will have to re-test all of those features and some of them may have broken.
- Customisations of a well defined type - such as custom page types or custom blog widgets - are going to be easier to upgrade than customisations that use sneaky tricks, such as the subsites module.
