Hi folks, i have this case: i want to update my solr 4.0 from trunk to solr 4.0 alpha. the index structure has changed, i can't replicate. 10 cores are in use, each with 30Mio docs. We assume that all fields are stored and indexed. What is the best way to export the docs from all cores on one machine with solr 4.0trunk to same named cores on other machine with solr 4.0 alpha. SolrEntityProcessor can be one solution, but does it work with this size of data? I want reindex all docs at once and not in "small" parts. I find no examples of bigger reindex-attempts with SolrEntityProcessor. Xslt as option two? What were the best solution to do this, what do you think?
Best Regards Vadim
