I have todo any action?No, neither gencache tdb is required for the upgrade, it is just a cache. We move records from gencache_notrans.tdb to gencache.tdb occasionally so that we avoid an expensive fsync() for every cache store, but have a 'recent' cache that is much more likely not to be corrupt on startup.
