No, I though about <iframe src="http://example.com"></iframe> to access "localStorage" with old origin (http://example.com) and copy the data.
Anyway, I decided to leave "old" users on "http", so it is not a serious problem.

Hi,
 
Is the iframe (or can it be) served over HTTPS?

Hello,
 
I want to migrate my site to HTTPS, but how could I save users "localStorage" ? As <iframe> is blocked, I cannot copy the data.
