Hi all, with Solr 10 now on the horizon, I'd love to get some of the work in SIP-21 (https://issues.apache.org/jira/browse/SOLR-17111) done. Specifically the standardizing our system property names, as described in the document https://cwiki.apache.org/confluence/display/SOLR/System+property+naming+structure. I've created a JIRA: https://issues.apache.org/jira/browse/SOLR-17864 that covers migrating a set of properties. I'd love some review on the associated PR, https://github.com/apache/solr/pull/3312. Once that goes through a review, I'll open new JIRAs for batches of properties and I think it'll go pretty quickly. The first one is the biggest hurdle! I'm looking for a +1 ;-) I do not plan on backporting this, it's Solr 10 Only. I will add a page to the upgrade notes that covers the migration of the properties based on the excellent spreadsheet Jan put together! Eric
