Migrating SOLR statistics from DSpace 7.6 to 8.0 error

[Lewatle Johannes Phaladi]

Dear DSpace Colleagues,

I am getting the following error when trying to import stats on DSpace 8.0 from DSpace ver 7.6

firstly I run the following lines 

[dspace]/bin/dspace solr-export-statistics -i authority

[dspace]/bin/dspace solr-export-statistics -i statistics

on 7.6 and copied solr-export to dspace 8.0 then run import stat as follows :

dspace@wiredspace:~/install/dspace8.0/bin$ ./dspace solr-import-statistics -i statistics
Exception: Error from server at http://127.0.0.1:8983/solr/statistics: SolrCore 'statistics' is not available due to init failure: Error opening new searcher

I would check the logs of the Solr instance used for your DSpace 8.0
instance, to see why it is failing to open new searchers on the
'statistics' core.

Hi DSpace Team,

I am using solr 9.0 version!

I would double-check that. The log that you provided suggests to me
that it was written by Solr 8.7 configured as for Solr 9.0.

Hi Mark and DSpace Colleagues,

I will down grade SOLR to version 8.11.1 since it is working well on DEV site, will communicate the outcomes once completed.
