fiberglass batt under cellulose

hello all, long time viewer/reader, 1st time homeowner/poster...

so, got a little early 1950's era home, looking to improve a bit. Was looking to add some blow-in cellulose to the attic, and while doing so realized there is some fiberglass batts under the cellulose, with paper side faced away from the living area! does not feel damp or smell, but now I wonder if I really want to add more cellulose on top (yes!), probably best bet is to remove the fiberglass as much as possible. Seems that I read on here if your cellulose is deep enough, a vapor barrier isn't nescessary. And fyi, I live in the Sierra Nevada Mountain Range, and already have had snow this week, so really anxious to keep my heat, lol.
