For example, Aela is my steward at Heljarchen Hall, and due to mistakes in building on my part I don't have enough room to adopt kids, therefore I need to move (since you can't redesign the home once it's built).
If I was to build a new house, could I make Aela my steward there as well by the same method as the first time (have her follow you to your new house), or would I have to get a new steward?
