My new code uses d3d9 surface while another old code uses ddraw7 surface. Can I copy data between these two? Except the slow lockrect

Different versions of the same interface (DirectGraphics) are not interoperable.

The best you could probably do is Lock the source surface, copy it to system memory (a big array), then Lock the destination and copy it from your array.

I'm surprised you can setup DD7 and D3D9 on the same device.

I thought that the DirectX was left in DX 9.0 and that you couild use DD7 surfaces?
