-------------------------------------
FYI we have dedicated documentation for this routine task:
/dev-docs/lucene-upgrade.md
> Upgrade main and branch_10x to Lucene 10.4
> ------------------------------------------
>
> Key: SOLR-18143
> URL: https://issues.apache.org/jira/browse/SOLR-18143
> Project: Solr
> Issue Type: Improvement
> Reporter: Rahul Goswami
> Priority: Major
>
> Lucene 10.4 released last week and contains several important Vector search
> related changes. It also contains a critical enhancement which moves the
> MIN_SUPPORTED_VERSION (Version.LATEST-1) check to the segment level instead
> of requiring that the index be created in version no older than
> MIN_SUPPORTED_VERSION. This is necessary to be able to open the indexes
> originally created in Solr 8.x and upgraded via the recently introduced index
> upgrade capability (while on Solr 9.x).
