Will moving enclosures stress out my new BP too much?

I just got my first bp last Thursday, and I had a 10gal glass terrarium setup for her. After doing more research and realizing this isn't the best thing for her, I've ordered the supplies to make her a plastic tub temp enclosure instead. I've done a little bit of tank rearranging before that to try and help humidity levels (not going well) but other than that I've done my best to not bother her anymore than necessary.

My question is if it's best that I wait until after her first meal to move her into her new enclosure, or should I go ahead and move her before? I don't want to stress her out to the point that she won't eat. :(

Personally I would get the tub ready and offer the meal in the smaller tank. Hopefully she eats and then a few days after that move her. That will give her more time to settle and eat, while you get the tub dialed in.

I'll try that then, thank you!
