I should have been more clear about my usage of Updraft Plus. I am not a pro customer and I currently use the free version to backup the staging site. I also meant to type Updraft Plus *Migrator* Pro. I included it in my migration plan because they seem to make it easy, including the search and replace (following this: https://updraftplus.com/faqs/how-can-i-send-site-data-directly-from-one-site-to-another/). It also seems like it can be installed on multiple accounts. However, I am not completely set on using their pro plugin if it’s not the best option. I have removed my post from their forum (thanks for the etiquette tip).
I appreciate all the advice, and seeing it laid out like this is helpful and reassuring. I see now that my situation is less complicated than I thought.
I would also like to make sure that my company’s WordPress account has access to the admin dashboard of the new, migrated site. Ideally I would like to pass it off to them completely, and keep my own account that I’m currently working form. It seems like if I use the Updraft Plus Migrator plugin, I should be able to accomplish this. Sorry to ask such an assumedly simple question in this forum. My lack of understanding about wordpress.org accounts has me puzzled.
