simple and working

I had use many solutions to migrate sites from dev to prod. This one is the best.
The only improvement for me would be in UI

I want two big buttons

1) on origin website ” make copy of this site”
2) on the target website “get content form …)

and say clear that after the migration the original wil still be in place as it is … and that the target website will be replace….

It’s not that obvious when you use it for the first time
