layback, migration is superrr eassyy for WA Members !
The migration process is one of the first things u learn in the WA-Training.
Moving a website is one of the things that's integrated in the WA website. I found this when i decided to go through the training again.
U don't need any plugin or do research for other ways to move your website or migrate your website, what is actually almost the same thing.
Check out the training yourself. And delete all other plugins from your website.
Let me know if it helps,
