Go for it! WeeWX will add some tables to your wview sqlite database. These are "daily summaries." It will take a while (how long depends on processing power) to "backfill" these summaries from the archive database, but it will keep you informed as to what is going on. I doubt there will be an issue with that, but you might want to make a copy of the wview database, rather than simply moving it over.
