You next install Latitude Studio 2.2.x. After installing, you use your backed-up files to restore your data and custom settings. You delete the directory containing your previous version, then start Latitude Studio 2.2.x.
To complete the upgrade to Latitude Studio 2.2.x:
If you have changed the location of anything normally kept in endeca-portal/data, such as your data source definitions, JCR repository, or Lucene search indexes, restore and re-verify your custom locations as well.
If you are not using HSQL, you should have created a backup of your database connection strings earlier.
The license file is available from the Latitude Studio section of EDeN (http://eden.endeca.com).
Before you start to use the application, make sure that you wait until all of the components have been deployed and registered. To verify that the upgrade is truly complete, you can monitor the log files to see when all activity has stopped.
