I'm not sure you can upgrade BDB using cvt_cyrusdb directly. I think you can only do it by exporting to a neutral formal like skiplist, then updating BDB, and the converting the db's back to BDB. Another way should be to use the BDB upgrade tools for this. However, why don't you just get rid of BDB so you don't have to care about it in future? Any reason you can't convert to skiplist and leave BDB behind? If you're running a recent Cyrus version then that's strongly recommended and makes life much easier.
