I agree.  This is easy to patch in, as it is contained in a single
class that can be run using 'bin/dspace dsrun
org.dspace.util.SolrUpgradePre6xStatistics' once the single source
file has been added to [dspace-source] and compiled.  I've needed to
do this on 5_x and 6_x test instances recently, and I'm planning to
add it to a production 6.2 instance that was upgraded from 5_x.

Re: [dspace-tech] Migrating SOLR stats from DSpace 5 to 6?

[Terry Brady]

Anne,

If you have a test system that you can test with, I recommend you try
running the following tool..

https://github.com/DSpace/DSpace/blob/dspace-6_x/dspace-api/src/main/java/org/dspace/util/SolrUpgradePre6xStatistics.java


In the meantime, some of the XMLUI statistics pages should have logic to
use either the UUID or the legacy id.

[dspace-tech] Migrating SOLR stats from DSpace 5 to 6?

[Anne Lawrence]

We are migrating from DSpace 5 to 6. We created a new instance of DSpace 6 
and copied the database to it. We migrated this database to DSpace 6 and 
ran the SOLR indexing successfully. (One thing new about the 6 instance is 
that we are using nginx, so we had to configure that.) In DSpace 5, we 
found that solr-export-statistics and solr-import-statistics appeared to do 
nothing, so we tarred and  copied the /dspace/solr/statistics/ to new 
machines as a way of migrating the SOLR stats. When we did this for this 
new DSpace 6 instance, no statistics display, probably because the SOLR 
records use IDs rather than UUIDs. I notice that there is a tool scheduled 
for DSpace 6.4, "Upgrade Legacy DSpace Object Identifiers (pre-6x 
statistics) to DSpace 6x UUID Identifiers 

," but we'd prefer not to wait for that. Does anyone have suggestions for 
working this out? 

Thanks,
