Should I Change My Author Name When I Get Married?

I just got engaged this weekend (!!!) and I want to know pros and cons of changing my author name after I get married. I have a website and email list, but do not have any books published yet (although I have published articles). I have a couple of questions and would love answers to any of these (especially from authors who have navigated this)!

1. Both my website hosting and domain are up for renewal this month. If I change my author name, can I just switch my hosting (I’m using SiteGround) to a new domain or would I have to buy it again? If the hosting would not transfer to a new domain, is there a way to export my site design and re-install Divi on a new site without purchasing it again?

2. I will be changing my name legally, which would turn my current author name into a pen name. Are there any legal or privacy issues associated with this? Any benefits with going one way or another?
