  • This line was added.
  • This line was removed.
  • Formatting was changed.

  • XMLUI and JSPUI are no longer supported or distributed with DSpace. All users should immediately migrate to and utilize the new Angular User Interface.
  • ElasticSearch Usage Statistics have been removed.  Please use SOLR Statistics or DSpace Google Analytics Statistics.
  • Configuration has been upgraded to Apache Commons Configuration version 2. For most users, you should see no effect or difference. No DSpace configuration files were modified during this upgrade and no configurations or settings were renamed or changed. However, if you locally modified or customized the [dspace]/config/config-definition.xml (DSpace's Apache Commons Configuration settings), you will need to ensure those modifications are compatible with Apache Commons Configuration version 2.  See the Apache Commons Configuration's configuration definition file reference for more details.

  • Database: Make a snapshot/dump of the database. For the PostgreSQL database use Postgres' pg_dump command. For example:

    Code Block
    pg_dump -U [database-user] -f [backup-file-location] [database-name]


  • Assetstore: Backup the directory ([dspace]/assetstore by default, and any other assetstores configured in the [dspace]/config/dspace.cfg "assetstore.dir" and "assetstore.dir.#" settings)
  • Configuration: Backup the entire directory content of [dspace]/config.
  • Customizations: If you have custom code, such as themes, modifications, or custom scripts, you will want to back them up to a safe location.
  • Statistics data: what to back up depends on what you were using before: the options are the default SOLR Statistics, deprecated Elasticsearch Usage Statistics, or the legacy statistics. Legacy stats utilizes the dspace.log files, Elasticsearch stats stores data in [dspace]/elasticsearch, SOLR Statistics stores data in [dspace]/solr/statistics. A simple copy of the data directory should give you a point of recovery, should something go wrong in the update process. We can't stress this enough, your users depend on these statistics more than you realize. You need a backup.
