To upgrade your database, you must dump all data from the VOS 5.x database and re-load it into VOS 6.x. Complete instructions may be found here. ***IMPORTANT NOTE*** for upgraders from earlier 6.x versions: The database file format has not changed, but the introduction of a newer RDF index requires you run a script to upgrade the RDF_QUAD table. Since this can be a lengthy task and take extra disk space (up to twice the space used by the original RDF_QUAD table may be required during conversion) this is not done automatically on startup. Complete instructions may be found here.
