Hi all,
I’m attempting an upgrade from DSpace 1.8 directly to 4.1 on a new
server but am running into a problem. Along with the asset store and
DB, we are wanting to preserve our viewing stats. After migration, if I
run:
/usr/local/dspace/bin/dspace stats-util -b
then I am getting the following Java traceback.
Exception: Document is missing mandatory uniqueKey field: uid
org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:

This error message does not occur if I run “dspace stats-util -b” on our
DSpace 1.8 server.

A summary of the steps that I’m taking are:
1. Copying across /usr/local/dspace/solr/statistics/data to the new server.
2. Doing a rsync of the asset store:
rsync -av --exclude=.snapshot --exclude=log
/usr/local/dspace/assetstore/ newserver:/usr/local/dspace/assetstore/
3. Exporting / importing the PSQL database from the old to new server.
4. Applying DB schema database_schema_18-3.sql followed by
database_schema_3-4.sql
5. Running /usr/local/dspace/bin/dspace checker -l -p
6. Starting tomcat on the new server and running:
/usr/local/dspace/bin/dspace index-discovery
Then I'm attempting to run "/usr/local/dspace/bin/dspace stats-util -b"
which is when the error message occurs.
After Step 6, I have also tried:
/usr/local/dspace/bin/dspace stats-util -o
/usr/local/dspace/bin/dspace stat-general
/usr/local/dspace/bin/dspace stat-initial
but am still running into the above error message upon running
“stats-util -b”.
If anyone could assist me with this it would be appreciated.
With Thanks,
Patrick Rynhart
