Murky said: You can find planter dollies with various types of wheels, from typical rubber ones to hard plastic to the round types you find on office furniture. All of them should be able to roll over those tiles easily. The weight of the planter will keep it from rolling, but you can also find some of the dollies with 2 wheels that lock just by pushing down on a small lever, preventing it from rolling, if you want to be sure.
Get a few friends to lift it once and you're done. Or if you're planning on repotting it anyway to try and straighten it first, just set the new empty pot on the plant dolly before you start filling in the dirt. No need for extra help then.
