I'm moving soon too, but my Grey is a lot younger than yours so I'm hoping it won't faze her much. I like your idea of taking them to visit the new place and getting them somewhat acclimated to it before hand. I read somewhere that it helps not to change the inside of their cage around before you move. As in, keep the same toys and whatnot in the same places in their cage before the move and after so at least the inside of their cage is familiar even if everything else is strange. Good luck!
