Migrating from 6.3 to 8.0

[rdias...@gmail.com]

Hello everyone.

After unsuccessfully trying to migrate from 6.3 to 7.x, I decided to go to 8.0 (at that time it was the latest version released).

I installed version 8.0 without content and then put the database and assetstore from version 6.3 in place. After running the database migration tool and some minor tweaks, I was able to open DSpace 8.0, but still without any content.

I can log in and see (as administrator - same account and password as in version 6.3) epersons and egroups, but no communities, collections, packages, items, bitstreams. Also, I have no log files and no errors (where could I see them if I have no logs?). As usual, it seems like something small like a comma is missing somewhere.

I decided to ask you guys before trying to install version 8.1 (with the same procedures I did with version 8.0), because I read somewhere that there is some problem with logrotate that may be preventing the logs from being written.

Any help will be greatly appreciated.

OS: ubuntu 24.04.1 LTS
Backend and frontend on the same machine.
openjdk version "17.0.13"
PostgreSQL 16.6
Tomcat 10

it seems to be you just miss to reindex the data to solr:

~/bin/dspace index-discovery -h

is your friend.
Before, you should read the docs carefully on solr update. Backup the
indexes (if you need the old ones, e.g. statistics).
The new solr is - if you installed it like assumed - in /var/solr.
Stop DSpace, solr and copy the solr/* folder from your new DSpace source
code to /var/solr/data/configsets (looks like: authority oai qaevent
search statistics suggestion
after, remove old files under configsets before) and change the file
permissions to solr

chown -R solr: /var/solr/

after that, restart solr,DSpace and try the index-discovery command.
Depending on the numbers ist will take a while.
Sorry, made from remembrance …but the key is re-indexing.
