This page is focused on upgrading from Sakai 20 to Sakai 21. It provides a link (below) to the Sakai 20 upgrade information that you will need if you are upgrading first to Sakai 20. Do that first and then come back here for the final steps to migrate to Sakai 21.
Please run ALL the scripts from your original version to the version to which you are upgrading. There are two sets of database upgrade scripts, one for MySQL and one for Oracle. Use the appropriate scripts for your database type.
The current version of Sakai at the time Sakai 21.0 was released was Sakai 20.2, therefore make sure you upgrade to 20.2 before upgrading to 21.0. If your on a later version of Sakai 20 then you may need to adjust your script to remove lines that you already have run in 20.3 from the 21 script.
2.0 Post upgrade conversion scripts
There are no post upgrade scripts to run
3.0 Browser Compatibility
Sakai is designed to work with modern browsers. Recommended browsers (those with the most QA testing effort against them) are Google Chrome, Safari, and Mozilla Firefox. Microsoft Edge should work fine. Sakai should work on most modern tablet and mobile devices. IE 11 is a poor browser choice as it is deprecated, slow, and has not implemented modern features. New functionality like Rubrics, may not work with IE 11.
