The first step in migrating to Latitude Studio 2.2.x is to back up the files from Latitude Studio 2.1.
To back up your Latitude Studio 2.1 files:
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, back up your custom location(s) as well.
This ensures that the Latitude Studio 2.2.x installation will not overwrite any of the existing files.
You will remove this directory when you complete the Latitude Studio 2.2.x installation.
