Hi, "What about upgrading major to major 1 to 2, 2 to 3, ... , 7 to 8?" I wouldn't recommend this time consuming activity, I am in line with other comments:
1) design your solution from scratch on Solr 8.x using your 1.4 config as a reference. 2) re-index (from your data source or worst case scenario, extracting it from your old Solr) Cheers -------------------------- Alessandro Benedetti Apache Lucene/Solr Committer Director, R&D Software Engineer, Search Consultant www.sease.io On Wed, 21 Apr 2021 at 08:02, shacky <shack...@gmail.com> wrote: > Hi, > I have a very old Solr installation (VERY old: Solr 1.4.1 running on Ubuntu > 12.04) which I would like to upgrade to the latest Solr version 8.8.2 on > Debian Buster. > > Will I be able to migrate the index or should I reindex all documents? > > Thank you very much! > Bye >
