Assistance Required: Migrating DSpace 6 to DSpace-CRIS 7

[Jayachristrayar S]

Dear all

I am in the process of migrating our current DSpace 6 installation to DSpace-CRIS 7. While I have made progress with some steps, I am encountering challenges with re-indexing the old files into DSpace-CRIS. I followed the standard DSpace backup and restore procedure, but it did not work as expected.

Below are the steps I have followed so far:

1. Database Backup:

   • Assumed the old version of DSpace is running.
   • Took a PostgreSQL database backup using the following commands:
     sudo su - postgres pg_dump dspace > dspace.backup
   • Stored the backup in /var/lib/postgresql/ and moved it to a secure location.

2. Backup of Assetstore and Log Folders:

   • Created backups of the assetstore and log folders using these commands:
     cd /media/<your_pc_name>/<External_Hard_Disk>
   •  sudo zip -r assetstore.zip /dspace/assetstore sudo zip -r log.zip /dspace/log

3. Restoration Steps to DSpace-CRIS 7:

   • Installed the latest DSpace version.
   • Restored the assetstore, log folders, and dspace.backup file to the home folder.
   • Stopped the Tomcat server:
     sudo service tomcat stop
   • Replaced the new assetstore and log folders with the old ones:
     sudo mv /home/assetstore /dspace sudo mv /home/log /dspace
   • Restored the database:
     sudo -u postgres psql DROP DATABASE dspace; CREATE DATABASE dspace; \quit sudo su postgres psql -f dspace.backup dspace exit
   • Enabled the pgcrypto extension:
     sudo su postgres psql --username=postgres dspace -c "CREATE EXTENSION pgcrypto;" exit
   • Upgraded the database:
     sudo /dspace/bin/dspace database migrate
   • Indexed the discovery:
     sudo /dspace/bin/dspace index-discovery -b sudo /dspace/bin/dspace filter-media sudo /dspace/bin/dspace index-discovery sudo /dspace/bin/dspace index-discovery -o
   • Restarted the Tomcat server:
     sudo service tomcat start

Despite following these steps, the migration process is incomplete, particularly regarding re-indexing. I would appreciate it if someone could guide me on migrating DSpace 6 to DSpace-CRIS 7 successfully, including addressing the re-indexing issue.

Thank you in advance for your support.
