New comment by digitalagedragon on void-packages repository https://github.com/void-linux/void-packages/issues/30041#issuecomment-828655807 Comment: http://orientdb.com/docs/3.0.x/release/3.0/Upgrading-to-OrientDB-3.0.html says 3.x is pretty backwards-compatible at least. Per http://orientdb.com/docs/3.0.x/release/Upgrade.html, though, it sounds like they consider moving an existing installation from 2.x to 3.x to require some degree of manual intervention? Not sure.
