Greetings. That document is quite exhaustive, but also makes the upgrade process look more complicated than it actually is in some cases. Last we upgraded one DSpace installation from 1.6 to 4.x within couple of hours. Following are the steps in a nutshell: 1. Install latest DSpace as per documented procedure in a fresh location (e.g. '/opt/dspace'). Shutdown Tomcat. 2. Copy the backup of old DSpace 'assetstore' in new location ('/opt/dspace/assetstore') with same permissions. 3. Upgrade the database with these steps: a) Take backup of old dspace database: pg_dump dspace > old-dspace-backup.sql b) Create new database: createdb -U dspace -E UNICODE dspace4 c) Import old dspace backup: psql dspace4 < old-dspace-backup.sql d) Upgrade database schema to the latest (from 1.6 to 4.x): cd /opt/dspace/etc/postgres psql dspace4 < database_schema_16-17.sql psql dspace4 < database_schema_17-18.sql psql dspace4 < database_schema_18-3.sql psql dspace4 < database_schema_3-4.sql 4. Make necessary changes in 'dspace.cfg' (e.g. to change database name to 'dspace4') and start Tomcat. 5. Re-index the collection: cd /opt/dspace bin/dspace index-discovery -f 6. Install cron for the dspace 4.x (old cron will not work) as given in this page: https://wiki.duraspace.org/display/DSDOC4x/Scheduled+Tasks+via+Cron All old user logins and content downloads will work in the new version.
