This page is focused on upgrading from Sakai 19 to Sakai 20. It provides a link (below) to the Sakai 19 upgrade information that you will need if you are upgrading first to Sakai 19. Do that first and then come back here for the final steps to migrate to Sakai 20.
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.

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.
