I found this question and it sounds like my solution, but on my IIS server the "Replace the current certificate" option is grayed out. I can't go the route of doing a standard replace because the current SSL cert is from Verisign and the new one will be from Godaddy. Will this ungray itself once I import the new cert into the temporary site? Thanks.
Yes, the Replace option will be available once there is another certificate installed on the system.
