Lucene Migration Query

Adarsh Sunilkumar
Hi Team,

Currently I am using Lucene 7.3, I want to upgrade to lucene 8.5.1. Should
I do reindexing in this case ?
Can I make use of backward codec jar without a reindex?



Thanks & Regards,
Adarsh Sunilkumar.

If you created your index with 7x, you don’t need to do anything, 8x will be able to operate with it. If you ever used 6x to index any docs you must reindex completely by deleting the entire index and starting over, or index to a new collection and use collection aliasing to seamlessly switch.

Best,
Erick
