WinSCP host keys

I have transferred from an older version of WinSCP to a newer version. I have upgraded from 5.9.3 to 5.21.5.

I understand that the later version stores the host keys in a different place.

Can anyone advise of a script/method to copy the SSH host key within the registry from local user to local system?

Many thanks

WinSCP never changed a location where it stores the host keys to. Why do you think so? What problem are you having?
