City social workers and charity workers woke the migrants before dawn Thursday, and they gathered their belongings calmly, watched over by police.
The operations took place at a large camp near the Gare d'Austerlitz train station in southeast Paris, and another in the 18th arrondissement of northern Paris.
Paris city hall said migrants are being bused to special migrant housing centers in Paris and the surrounding region, and offered help applying for asylum.
