Hi everyone,

this was true for Solr up until 7.x

For 8.x you *need* to reindex.

You'll need to reindex.

Upgrade of index is supported from one major version below.

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
