Copy any custom full text search files (dictionary, synonym, thesaurus, stop words) from the old to the new cluster. If you are trying to automate the upgrade of many clusters, you should find that clusters with identical database schemas require the same post-upgrade steps for all cluster upgrades; this is because the post-upgrade steps are based on the database schemas, and not user data.
