If you are upgrading from v4.x, you must upgrade to each intermediate version before installing this version. When upgrading from the previous version, v4.2.4 you will need to do the following:

  1. First, check for and correct duplicate email addresses, including duplicates due only to different case. This is a new requirement for this version.
    • See remove_duplicate_emails.txt for more information.
  2. Undeploy the previous version.
    • /glassfish4/bin/asadmin list-applications
    • /glassfish4/bin/asadmin undeploy dataverse.war
  3. Deploy this version.
    • /glassfish4/bin/asadmin deploy /dataverse-4.3.war
  4. Run the database update script.
    • psql -U <db user> -d <db name> -f upgrade_v4.2.4_to_4.3.sql
  5. Restart glassfish.
    • service glassfish stop
    • service glassfish start
  6. If you were running Two Ravens, enable it for this version.
  7. Run the incremental index to correct the targeting for citation links.

If you are upgrading from v3.x, you will need to perform a migration to v4.x since our application was redesigned and the database schema are completely different. This is a significant undertaking. Please contact us (support at before beginning. Also refer to our migration google group for additional support and information:

Please note: v4.x does not currently support creating new handles though it will support existing ones. We intend to add this feature but have not yet scheduled this work.
