The risks you will face:
1) The obvious, it may be lost or stolen. Can you afford to lose family photos and you personal info?
2) Vibration. It addition to having your boxes roughly handled, ships will expose your gear to low frequency vibration for weeks on end.
3) Temperature. Most shipping isn't climate controlled, so you may get condensation.
4) Incompatibility. Chances are where you are going will have difference power, communications, space and environmental
Recommendation. Sell everything you can't replace and buy new at the destination. Almost for sure where you are going will have difference standards which apply to electronics, furniture, appliances and clothes. Backup everything twice. Leave a copy in the cloud, and one with friends/family.
