Re: Help for importing large data (approx. 8GB) from old solr version to new solr version

[Paras Lehana <pa...@indiamart.com>]

Hi Ken,

I also recommend at least reading if not following "Taking Solr to
Production":
https://lucene.apache.org/solr/guide/8_4/taking-solr-to-production.html.

Following this cleared my doubts regarding upgradation and core referencing
while made upgradation very easy and fast.

While starting Solr, you can also define Solr Home (where your older core
lives) by using -s option.
