OK, you have two options: 1.1> do NOT construct IDs with the version. Have two separate fields, id (which is the <uniqueKey> in your schema and a _separate_ field called tracking (note, there’s already by default an _version_ field, with underscores, for optimistic locking, do not use that).
1.2> Index the new version of the doc with the exact same ID and a new version and a new “tracking” value Solr will replace the old version with the new version based on the ID. Second: Before you re-add the doc, issue a delete-by-query that identifies the document, something like q=id:123* _How_ you determine that there is a new version of the doc you need to index is outside of Solr, you have to do that yourself.
