There is no minimum height for junction boxes per NEC. Any use of a junction box that would be subjected to harsh conditions because of its height would have to be rated for the condition. Personally, in outdoor areas, I like to keep boxes at least 18" above grade in areas that get snow.

How do I move thermostat from downstairs to upstairs?
There are two types of thermostats. One is line voltage and will require a splice be made in the old thermostat junction box . From the old box a new cable has to be pulled to the new thermostat junction box. This wire must be of the same size as the existing wire.The other type of thermostat is low voltage thermostat. This uses usually # 22 size wire and because it operates on low voltage it does not need a junction box to make a splice in. Solder and tape the new wire on to the old piece and then take it to where the new thermostat is to be located.
