Piano Tuning, Restoration & Repair Job - Durbanville, WC, 7551

I would just like some advice. I am moving an upright piano from Durbanville to KZN, Margate on the hibiscus coast. I just want to know if there is any treatment the piano needs before movement. I believe altitude and humidity can play a huge role in piano maintenance, sound and upkeep, and I do not want to cause any damage. Could someone please contact me about this? Or could I call someone about this? I am struggling to find anyone's contact details.
