### Backwards Compatibility

• eXist-db v4.4.0 is backwards binary-compatible as far as eXist-db v3.0, but not with earlier versions. Users who are upgrading should always consult the Upgrading Guide in the documentation.
• NOTE: The version of Dashboard that was installed with eXist-db 3.6.1 (or earlier) is incompatible with eXist-db 4.0.0 and newer. If you plan to migrate your entire database to eXist-db 4.4.0, you MUST take one of the following steps to allow Dashboard to work after the upgrade:
  1. If you have not yet installed eXist-db 4.4.0, open Dashboard > Package Manager, and upgrade Dashboard to 0.4.10, or run this script in eXide or the Java Admin Client: repo:install-and-deploy("http://exist-db.org/apps dashboard", "http://demo.exist-db.org/exist/apps/public-repo/modules/find.xql"). Then you may safely install eXist-db 4.4.0 and use Dashboard.
  2. If you install eXist-db 4.4.0 before upgrading Dashboard, run this script in eXide or the Java Admin Client: repo:install-and-deploy("http://exist-db.org/apps/dashboard", "http://demo.exist-db.org/exist/apps/public-repo/modules/find.xql"). Then you may use Dashboard.
