If we had a poll about VFTs all over the net, I think the really biggest and top most frequently asked question for new VFT keepers is about Dormancy. At least those who know their stuff and is beyond.. can I feed it meat? Or will it bite me?
After a few years of keeping them, Heck I am still confused with it. I have openly admitted that now I keep VFTs like Annuals, if they die after a year, I accept it... of course I still hope that I can find a way to beat or go with the flow with this dormancy thing.
All I know is that the VFT is not happy when it is very slow to close already, in fact at the point you are in a bit of trouble already. I have so far only experimented with 1 Bulb in the Ref for dormancy, nothing yet coz it's just there 1 month. Anyways search this forum for VFT Dormancy, you will be filled with so many info, you will go crazy. for us in tropical countries, the alternatives are to do dry dormany (do a search on that here as well) or the Ref method, unpot, clean stick in Sphagnum moss and stick in the ref for a few months, then repot after that. I would say I am doing the Dry dormancy without even thinking about it, and get mediocre results in my case only.
As for the acclimitization, I feel that if you can find a good place for it, put it there and find a way to slightly shade it. In my opinion only, going back and forth like what you described is not only tiring, it also changes a lot of other environmental factors like humidity, temperature, etc. For me often new VFTs are put where they are going to be permantly located, they do fine, they take 1 week or more to start growing new leaves, then you know they are becoming happy. Good luck!
Oh and I agree with Tseztan, your plant is far from wanting dormancy yet
