Hi SOLR team,
Please may I ask for some advice regarding upgrading the SOLR version (ours currently running on solr-5.2.1) to the latest version? Currently looking at incremental version upgrades (from the SOLR Upgrade notes I was hoping to move up to 6.x), But also wanted to know if moving directly to 8.x or 9.x is a possibility? Ours is a standalone one with no collections and just 1 core. With approx.. 3M documents What would be the most efficient way to upgrade and test? Much appreciate the advice, Thank you! Lulu
