Yes you need to reindex. Update solrconfig, schemas to leverage the later feature of the version (some datatypes are now more optimal others are deprecated.
Update Solrconfig.xml and schema to leverage the latest datatypes , features etc.. Create new collection based on newest config. Use your regular Index process to move documents to new collection. Check if new collection works and has expected performance. Delete old collection.
