I've 2 site in invision, one is just pruchase with the plan called ite "A", the other one is trial version called it "B" and it expired.

 

Can I trasnfer B site to A ? Because if cant need to rebuild whole site

You would not generally transfer everything from one cloud platform to another. Could I ask why it is you would want to do this? Is it just because you have the wrong one active at present?
