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.

Dear Dr. Amin, Please explain how it is different from the instructions recommended by developers which is available at : ( https://wiki.duraspace.org/display/DSDOC4x/Multi-Version+Upgrade+Tips+and+Tr... ) under the topic " Install Fresh and Upgrade your Data " . The same thing i have mentioned in document, further that document contains installation on production environment recommended by developers as well as the solutions of the problem which i faced after migration from 1.2.1 to 4.2 . Further can you solve my one problem which i am facing after that migration? i.e xmlui search/discovery is not working but browse works fine, at the same time jspui all features work brilliantly, the problem which i get after clicking the advance search of xmlui is: An error has occurred Go to DSpace home java.lang.NullPointerException: Cocoon stacktrace [show] Java stacktrace [show] Java full stacktrace [show] Please keep me replying with solution on forum because many will be benefited which coulod not be resolved by even dspace mailing list. I hope to get solution as you have good experience on DSpace i think? On Fri, 07 Nov 2014 13:47:22 +0530 "Dr. Saiful Amin" wrote
