i've spent a lot of resources moving a lot of buildings this week and I see no prob with it at all. I planned where I wanted to put the buildings (test server is a good place to help with this), did lots of adv's to get the resources and then finally did the moves. I enjoyed the whole experience.
most were lvl5 buildings and I am now planning which lvl6 buildings to demolish. if I could move buildings for free, I'd just shuffle things around aimlessly and soon get bored.
