If your statistics are using Solr, there will be a dspace/solr/statistics folder.
I had to bring statistics from version 1.8.3 to 4.2. I optimised under 1.8.3 and then 4.2, but found that the old records were missing uid, _version_ and statistics_type fields. I ended up copying all the records and deleting the originals. I don't know whether that was a sensible solution, but it seemed to work. I ran the following (sorry, it's Python) to talk to Solr under 4.2. The debug was in there to allow investigation if anything unexpected happened (it didn't). #! /usr/bin/python import urllib2 import json import pdb BATCH_SIZE=10000 REQ_URL='http://127.0.0.1:8080/solr/statistics/select?q=*:*+AND+-uid:[*%%20TO%%20*]&wt=json&indent=true&rows=%d&start=%d' UPDATE_URL='http://localhost:8080/solr/statistics/update' start = 0 query_res = urllib2.urlopen(REQ_URL%(BATCH_SIZE,start)) if query_res.getcode() != 200: pdb.set_trace() doc_list = json.load(query_res)['response']['docs'] while doc_list: start += BATCH_SIZE update_req = urllib2.Request(UPDATE_URL,json.dumps(doc_list),{'Content-type':'application/json'}) update_res = urllib2.urlopen(update_req) if update_res.getcode() != 200: pdb.set_trace() print "Added %d" % start query_res = urllib2.urlopen(REQ_URL%(BATCH_SIZE,start)) if query_res.getcode() != 200: pdb.set_trace() doc_list = json.load(query_res)['response']['docs'] # If the above goes OK, we can delete everything without a uid field update_req = urllib2.Request(UPDATE_URL,'{"delete":{"query":"-uid:[* TO *]"}}',{'Content-type':'application/json'}) update_res = urllib2.urlopen(update_req) if update_res.getcode() != 200: pdb.set_trace() commit_res = urllib2.urlopen(UPDATE_URL+'?commit=true') if commit_res.getcode() != 200: pdb.set_trace() Steven Hayles Systems Analyst IT Services, University of Leicester, Propsect House, 94 Regent Rd, Leicester, LE1 7DA, UK T: +44 (0)116 229 7950 E: s...@le.ac.uk The Queen's Anniversary Prizes 1994, 2002 & 2013 THE Awards Winners 2007-2013 Elite without being elitist Follow us on Twitter http://twitter.com/uniofleicester or visit our Facebook page https://facebook.com/UniofLeicester > On 1 February 2015 at 14:43, . . <alsap...@hotmail.es> wrote: > >> Hello, we DSpace version 1.6 running (we do not have installed).
