The 21-year-old previously played for Saracens and Blackheath before becoming a full-time member of the Sevens squad.
However, after impressing on the IRB World Series circuit, Caprice has now signed a two-year deal to move to France.
Caprice said: "I'm pretty excited about the move and really looking forward to it. It was a hard decision to make but I'd always wanted to play in France.
"They're one of the top teams in Europe and you only have to look at the players there to see that the chance to train day-in, day-out with them is great. The coaching staff are brilliant and I was blown away by the place when I went over there."
England Sevens head coach Ben Ryan has hailed the development Caprice has made since being part of the first intake of full-time players.
Ryan said: "Dan is a great example of a sevens player going on to be noticed by a top European team.
"We wish him every success with the next stage of his career and he's developed really well during the time he's spent with England Sevens. In a short space of time with us he's gone from being an academy player to a world-class sevens player."
