Change PS3 HDD and keep trophies

Hi guys, i will replace the default 160gb ps3 slim hdd with a 1tb. My PS3 is at 4.86 rebug, and i saw in this video https://www.youtube.com/watch?v=PEYCT6WLeAI that rebug has a custom utility to make this transfer. But will not transfer trophies just like any other method. I read somewhere that you can manually copy the trophy files to the new hdd but not sure if this will work.

I never went online on psn on this...
