We recently did the same thing! Loving our much bigger yard and deck!
It can be done...you have to work hard to get things as organized as possible (we even painted the daycare area over the weekend so it would be ready for Tuesday we re-opened), but just work to at least have that space completely done with familiar toys and furniture so the babies aren't in a completely new environment. As long as you're there, the transition should be smooth. Good luck!!
