Reindexing is not necessary. Drop in 3.4 and go.
For this sort of scenario, it's easy enough to try using a copy of your
<SOLR_HOME> directory with an instance of the newest release of Solr. If the
release notes don't say a reindex is necessary, then it's not, but always a
good idea to try it and run any tests you have handy.
