When upgrading from 2.x, expect a new and refreshed editor. Many features will be familiar, but some have also been removed or operate differently now. And of course, there’s a lot of new features for you to use as well.
During the first upgrade to Redactor 3, your v2 system settings will automatically be converted into a configuration set named “Imported from Redactor 2”.
This imported set will be as close as a match to your old configuration as possible, but keep in mind not every old setting has a new option.
Your imported set will be automatically enabled. Please test it to make sure it was properly imported and works the way you expect it to.
To help ease with upgrading when using custom CSS, the v2 “redactor-editor” class is added to your imported configuration set (in Appearance > Content style class); this will not be present on the standard configuration sets. Learn more about custom styling in v3
The JSON structure for custom formatting has changed in v3 and will need to be manually updated.
Important: downgrading from 3 to 2 is not supported. If you’re not sure yet if you want to start using Redactor 3 right away, test the upgrade on a development site and only upgrade production when you’re happy.
Old system settings from v2, with a few exceptions, are removed on the first upgrade to v3.
Tip: start fresh
While the automatic import is useful, we do recommend configuring Redactor 3 from scratch. Take a good tour of the new configuration sets to find out what Redactor 3 can do and use this as an opportunity to refresh your configuration.

Dropped or changed features
Please note this list may be incomplete
- Allowed/denied tags and cleanup in general works differently now. See the Cleanup tab for details of what you can configure in v3.
- The image float margin from v2 has changed. Previously you would set a margin for left and right floats separately, in v3 you set a single margin (in the Media tab) which will automatically be applied to the proper side of the image.
- Source code highlighting with Ace is no longer supported. Only Codemirror is now available (enabled by default).
- The syntax for some plugins (like Clips) has changed. In most cases these will be automatically converted by the configurator. See the configurator for details.
- Changing the available colors for the fontcolor plugin is no longer supported.
The following custom plugins are no longer supported. Let us know if you think we should rebuild them for v3.
- replacer (find & replace window)
- speek (read content out loud)
