Will non-USB 3 Lightning to Camera Adapter work for new iPhone Migration?

Will the Lightning to USB Camera Adapter (pictured below, with no additional Lightning port) work for the new iPhone Migration, where data is transferred from old to new iPhone via cable?

Apple’s support page for migration links specifically to the Lightning to USB 3 Camera Adapter, which is visibly different with an additional female Lightning port. I currently have the older adapter, and am wondering:

• Will this older adapter work for iPhone Migration?
• If so, will the data transfer speed be capped to USB 2 speeds?

Solution 1:

Apple's support documents only list the "Lightning to USB 3 Camera Adapter" as compatible with this process. If you want to be guaranteed that it works - use that adapter.

You can test your old adapter without fear of breaking. If the "Lightning to USB Camera Adapter" works for you, it will be capped at USB 2 speeds, as it doesn't support higher speeds.
